In investing, what is comfortable is rarely profitable. – Robert Arnott (Quote source: https://trwsb.wordpress.com/2020/11/12/fear-greed/)
Purpose: Learn class inheritance, composition, multi-file class implementation, and make utility. Points: 100 Assignment: Design and implement four C++ classes- stockInvestor, investorType, stocksPortfolio, and fileIO.
The assignment outcome is to generate an investors’ portfolio report that shows their profit and or loss in their investments. In stocksMain.cpp, the objects of multiple classes are declared. With the use of constructors, setters, getters, we implement the functions to write the investors’ data to a investorsData.txt file.
During this process, the portfolio report is printed on terminal. Using fileIO class, read the data from investorsData.txt file, calculate profits and loss. Finally, write the portfolio reports to investorsPortfolio.txt file.

(Base class_1) class stockInvestor { }; (Derived class_2) class fileIO:public investorType, public stocksPortifolio { }; studentInvestor is a base class (Base class_1) encompasses basic investor’s information like first name, last name and ID; This class default constructor, parameterized constructors, setter functions, to initialize member variables according to the parameters.
Also getter functions to return member variables. (Derived class_1) class investorType :public stockInvestor { }; (Base class_2) Class stocksPortifolio {-investorType invTypeObj; }; investorType is a derived class (Derived class_1) that has functions like: default constructor, constructor(parameters), setter (parameters) functions, getter functions(), and printData(ostream &).
This class includes typeName, stockName, stockCount, and stockPrice as member variables. It inherits first name, last name and ID from the base class stockInvestor. This class has constructors and setters to set the base class and its own class private member variables.
writeDataToFile(ostream &, investorType &) use getter functions to write the investors data to investorsData.txt file. Has-A Is-A Is-A Is-A stocksPortfolio is a base class (Base class_2) that has functions like: default constructor, constructor(parameters), setter (parameters) functions, getter functions(), writePriceChangesToFile(ofstream &), and printPriceChanges(ostream &).
This class includes priceOne, priceTwo, priceThree, stockValue, an object (invTypeObj) of investorType (Composition: has-a relationship) as member variables. With composition, the object(s) of investorType class only can access to investorType member functions.
The object of stocksPortfolio can not directly access the member functions of investorType class. You write the price changes (3 prices) of each investor’s stock to investorsData.txt file. printPriceChanges(ostream &) prints all the three prices on the terminal or to the output file according to the parameter passed.
The classes we will implement are as follows: • stockInvestor Class ◦ Implement a basic stockInvestor class(Base class_1), will track investors basic information and provide standard support functions for all investors. This will include first name, last name, and ID. This class has a default constructor, parameterized constructor, setter and getter functions.
To set the ID, you call setInvestorID(string id); In the implementation of setInvestor(ID) function, you call bool checkInvestorID(string tempID). The bool function returns true if the tempID meet the requirements else false. When the checkInvestorID(tempID) returns false to setInvestorID(string id), then this function prints an error message: Example: Error :- 318345 is invalid investorID for Dennis ◦ stockInvestor will be the base class as this will apply to any investor (Type- Personal or Trader).
The investorType class will inherit this functionality, so this class must be fully working before working on the investorType. ◦ print(ostream &output): It prints InvestorID, firstName, lastName. It prints the above details on the terminal if the parameter is cout. It prints the above details to an output file if the passed parameter is output. See the sample output for more details.
This function doesn’t print stars and dashes. • investorType Class ◦ Implement a class, investorType (Derived class_1), that contains typeName, stockName, stockCount, stockPrice as member variables. This class can set all above using setter functions individually. Along with the above member variables, every investor have the following details such as firstName, lastName, ID.
The parameterized constructor and setter functions are useful to set all the parameters of an investor. For this, you call base class (stockInvestor) constructors and setter functions as needed. ◦ The getter function(s) return the member variable accordingly. As the investorType is inherited from stockInvestor, the object of investorType can access its own member functions and also member functions of stockInvestor(base class).
In stocksMain.cpp, the objects of base classes and derived classes are declared. Few objects are declared with parameterized constructors and few are declared with no parameters. The object with no parameters can call setter functions to initialize investors data according to the parameters.
◦ You write the data of each investor such as firstName, lastName, ID, typeName, stockName, stockCount, stockPrice to investorsData.txt file through its member function: writeDataToFile(ofstream &outFile, investorType &tempObj).
[Hint: You call the getter functions with tempObj of investorType. ◦ print(ostream &output): It prints firstName, lastName, ID, typeName, stockName, stockCount, stockPrice. It prints the above details on the terminal if the parameter is cout. It prints to an output file if the passed parameter is output.
See the sample output for more details to match with stars and dashes. fileIO is a derived class (Derived class_2) that has a single function like: unsigned int readWriteDataFile(ifstream &inFile, ofstream &outData); The function reads investorsData.txt as an input file; After reading the parameters from file, use investorType constructors(parameters), and stocksPortifolio constructors(parameters) to set parameters accordingly.
Finally, calculate stockValues with original stock price, and three more price changes. Finally, write all the calculations, and the detailed report to investorsPortifolio.txt file. The function returns the number of entries(rows). • stocksPortfolio Class ◦ This stocksPortfolio class is a base class (Base class_2). This class includes priceOne, priceTwo, priceThree, stockValue, an object (invTypeObj) of investorType (Composition: has-a relationship) as member variables.
With composition, the object(s) of investorType class only can access to investorType member functions. The object of stocksPortfolio can not directly access the member functions of investorType class. You write the price changes (3 prices) of each investor’s stock to investorsData.txt file. ◦ printPriceChanges(ostream &) prints all the three prices on the terminal or to the output file according to the parameter passed.
◦ stocksPortfolio(double pOne, pTwo, pThree, investorType invTemp) is a parameterized constructor. Initialize the member variables according to the parameters passed. The approach is similar for the setter function that has all the above parameters. ◦ calculateStockValue(investorType invTemp, ostream &output): This is to calculate the stockValue on every price change
▪ Multiply stockPrice with stockCount (Here stockPrice is the initial price of stock) (both from investor type; use getters) ▪ Multiply stockCount with each new price and print statements accordingly ▪ Finally print stockValue: Show Loss/Profit accordingly ▪ call printPriceChanges(ostream &output) ▪ Check sample output for more details
◦ writePriceChangesToFile(ostream &output) const: Write priceOne, priceTwo, and priceThree to the investorsData.txt file. Check sample output, the prices should be in same line as id, name, etc. ◦ printPriceChanges(ostream &output) const: It prints priceOne, priceTwo, and priceThree. It prints the above details on the terminal if the parameter is cout. It prints to an output file if the passed parameter is output.
This function doesn’t include stars and dashes. This function must be called in calculateStockValue(investorType invTemp, ostream &output). • fileIO Class ◦ Implement a small class, fileIO class(Derived Class_2). This class is inherited from investorType and stocksPortfolio through public access specifier.
This class has no member variables and it contains only one member function. ◦ unsigned int readWriteDataFile(ifstream &inFile, ofstream &outData): This function does read and write operations on files. Declare local variables as needed. It reads data from investorsData.txt file; declare objects of investorType and stocksPortfolio; call constructors or setters to set the parameters that are read from text file; Call the functions print(parameter) and calculateStockValue(parameter); These functions must write the investors’ portfolio (report) to investorsPortfolio.txt file similar to the output that is printed on Terminal.
This function must print the total entries of investorsData.txt file that includes invalid data lines. Also, this function returns that total entries. ◦ In stocksMain.cpp, only one fileIO fObj is declared. You call the readWriteDataFile(parameters) with that object.
If you observe here, you read every line from investorsData.txt file one after other; declare objects of investorType and stocksPortfolio then initializing parameters through constructors and setters accordingly; You use the same objects to read the next line and so you overwrite on the previous data. This saves more memory space.
However, you don’t have separate allocation for each investor and so you can not make changes flexibly, or you can’t access the data of each investor dynamically. However, with the method we followed to declare objects in stocksMain.cpp, gives more flexibility to make changes on each investor. In short, both approaches have their own pros and cons.
Inheritance, composition and fundamental concepts are important in object oriented programming and it is essential to fully understand. Refer to the textbook and class lectures for additional information on inheritance and composition.
Development and Testing In order to simplify development and testing, the project is split into four parts: stockInvestor, investorType, stocksPortfolio, and fileIO classes. • The stockInvestor can be developed first and this class can be tested independently of the other class. This class sets firstName, lastName, and ID. • The investorType (Inheritance: is-a relationship) must be developed next (before stocksPortfolio). This class is inherited (public) from stockInvestor (base class).
This class can be tested after implementing base class but has no dependency with other classes. This class has typeName, stockName, stockCount, and stockPrice as member variables. • The stocksPortfolio (Composition: has-a relationship) must be developed next. This class has parameters like priceOne, priceTwo, priceThree, stockValue, an object (invTypeObj) of investorType (Composition: has-a relationship) as member variables.
The above parameters are set using stocksPortfolio functions and the investorType member functions can be accessed with the object of investorType only (composition). So, you have to implement investorType before you implement this class. • The FileIO (Inheritance: is-a relationship) must be developed last as this is derived from investorType and stocksPortfolio classes.
This class has only one member function with two parameters. Parameter one is ifstream, to read from investorsData.txt file. Parameter two is ofstream, to write the investors’ portfolio reports to investorsPortfolio.txt file. Submission: • All files must compile and execute on Ubuntu and compile with C++11. • Submit source files ◦ Submit a copy of the source files via the on-line submission. ◦ Note, do not submit the provided header files and stocksMain.cpp (we have them).
• Once you submit, the system will score the project and provide feedback. ◦ If you do not get full score, you can (and should) correct and resubmit. ◦ You can re-submit an unlimited number of times before the due date/time. ◦ Check the maximum attempts you can submit within an hour. • Late submissions will be accepted for a period of 24 hours after the due date/time for any given lab.
Late submissions will be subject to a ~2% reduction in points per an hour late. If you submit 1 minute – 1 hour late -2%, 1-2 hours late -4%, … , 23-24 hours late -50%. This means after 24 hours late submissions will receive an automatic 0(zero). Program Header Block All program and header files must include your name, section number, assignment, NSHE number, input and output summary.
The required format is as follows: /* Name: MY_NAME, NSHE, CLASS-SECTION, ASSIGNMENT Description: Input: Output: */ Failure to include your name in this format will result in a loss of up to 5%. Code Quality Checks A C++ linter1 is used to perform some basic checks on code quality.
These checks include, but are not limited to, the following: • Unnecessary ‘else’ statements should not be used. • Identifier naming style should be either camelCase or snake_case (consistently chosen). • Named constants should be used in place of literals. • Correct indentation should be used. • Redundant return/continue statements should not be used. • Selection conditions should be in the simplest form possible. • Function prototypes should be free of top level const.
Not all of these items will apply to every program. Failure to to address these guidelines will result in a loss of up to 5%. stockInvestor Class Implement a basic stockInvestor class to provide basic information of an investor. The stockInvestor UML class diagram is as follows: stockInvestor -firstName, lastName, ID: string +stockInvestor() +stockInvestor(string fName, string lName, string id) +setStockInvestor(string fName, string lName, string id): void +setInvestorID(string id): void +checkInvestorID(string investorIDTemp) const: bool +setName(string fName, string lName): void +getID() const: string +getFirstName() const: string +getLastName() const: string +print(ostream &output) const: void Function
Descriptions: The following are more detailed descriptions of the required functions. • stockInvestor() is a default constructor that initializes firstName, lastName, and ID. • stockInvestor(string fName, string lName, string id); This parameterized constructor is used to initialize the member variables according to the parameters in the constructor body. • void setStockInvestor(string fName, string lName, string id);
This setter function is used to initialize the member variables according to the parameters. • bool checkInvestorID(string investorIDTemp) const; return false if the ID is less than 6 characters Check the following conditions for an investors ID: return false if the first character is not upper case return false if the first character is not ‘T’ or ‘P’. return false if the remaining characters are not the numbers between 0 to 9. return true if all the conditions are met.
• void setInvestorID(string id); if checkInvestorID(id) returns false print an error message and assign the id Example: Error :- 318345 is invalid investorID for Dennis if checkInvestorID(id) returns true assign id to ID(member variable) 1 • void setName(string first, string last); This function is to set firstName and lastName according to the parameters. • string getID() const; This function is to return the ID. • string getFirstName() const; This function is to return the firstName.
• string getLastName() const; This function is to return the lastName. • void print(ostream &output) const; This function is to output the firstName, lastName and ID. Prints on terminal if cout is the parameter. Prints on to output file if the parameter is output. investorType Class Implement the Derived class_1 named investorType which is inherited from stockInvestor class.
This class deals with investor details like ID, firstName, lastName, typeName, stockName, stockCount, stockPrice. The investorType UML class diagram is as follows: investorType -typeName: string -stockName: string -stockCount: int -stockPrice: double +investorType() +investorType(string id, string fName, string lName, string tyName, string stName, int stCount, double stPrice, ostream &output) +setInvestorInfo(string id, string fName, string lName, string tyName, string stName, int stCount, double stPrice): void +setType(string tyName): void +setStockName(string stName): void +setStockCount(int stCount): void +setStockPrice(double stPrice): void +getID() const: string +getFirstName() const: string +getLastName() const: string +getType() const: string +getStockName() const: string +getStockPrice() const: double +getStockCount() const: int +print(ostream &output) const: void
+writeDataToFile(ofstream &outFile, investorType &tempObj): void Function Descriptions: The following are more detailed descriptions of the required functions. • investorType() is a default constructor to initialize all the member variables. • investorType(string id, string fName, string lName, string tyName, string stName, int stCount, double stPrice, ostream &output) is a parameterized constructor to initialize the member variables according to the parameters in the constructor body.
Expected Error messages for invalid ID, stockCount, stockPrice. Examples are given below: Invalid ID; No calculations for Dennis; ID 318345 James’s stock count is invalid Ryan’s stock price is invalid • void setInvestorInfo(string id, string fName, string lName, string tyName, string stName, int stCount, double stPrice) is to set the member variables according to the parameters. • void setType(string tyName) is to set the typeName member variable
• void setStockName(string stName) is to set the stockName member variable • void setStockCount(int stCount) is to set the stockCount member variable • void setStockPrice(double stPrice) is to set the stockPrice member variable • string getID() const return ID • string getFirstName() const return firstName • string getLastName() const return lastName • string getType() const return typeName • string getStockName() const return stockName • double getStockPrice() const return stockPrice • double getStockCount() const return stockValue • void print(ostream &output) const; Check sample output for more details. You will use few iomanip library for formatting.
In this function print stars and dashes using the following instructions: string stars; stars.append(65, ‘*’); cout << stars << endl; string dashes; dashes.append(50, ‘_’); This function prints the following: typeName, firstName, lastName, ID, stockName, stockCount and stockPrice If the parameter is cout, prints on terminal. If the parameter is output, prints to an output file. • void writeDataToFile(ofstream &outFile, investorType &tempObj) This function writes ID, firstName, lastName, typeName, stockName, stockCount and stockPrice to investorsData.txt file.
[Hint: call getter functions with tempObj] stocksPortfolio Class Implement the Base class_1 named stocksPortfolio. This class has priceOne, priceTwo, priceThree, stockValue, an object (invTypeObj) of investorType (Composition: has-a relationship) as member variables.
The stocksPortfolio UML class diagram is as follows: stocksPortfolio -priceOne: double -priceTwo: double -priceThree: double -stockValue: double -invTypeObj: investorType +stocksPortfolio() +stocksPortfolio(double pOne, double pTwo, double pThree, investorType invTemp) +setPortfolio(double pOne, double pTwo, double pThree, investorType invTemp): void +calculateStockValue(investorType invTemp, ostream &output): void +writePriceChangesToFile(ostream &output) const: void +getInvestorPrice() const: double +getPriceOne() const: double +getPriceTwo() const: double +getPriceThree() const: double +getStockValue() const: double +printPriceChanges(ostream &output) const: void Function
Descriptions: The following are more detailed descriptions of the required functions. • stocksPortfolio() is a default constructor to initialize all the member variables • stocksPortfolio(double pOne, double pTwo, double pThree, investorType invTemp) is a parameterized constructor to initialize the member variables according to the parameters in the constructor body. • void setPortfolio(double pOne, double pTwo, double pThree, investorType invTemp); is to set the member variables according to the parameters.
• void printPriceChanges(ostream &output) const prints the three price changes on terminal or to the investorsPortfolio.txt file according to the parameter passed • void calculateStockValue(investorType invTemp, ostream &output) ▪ Initial stockValue = Multiply stockPrice with stockCount (Here stockPrice is the initial price of stock; both from investor type; use getters) ▪ Multiply stockCount with each new price (3 prices) and print statements accordingly ▪ Finally print stockValue: Show Loss/Profit accordingly ▪ Profit: If stockValue of priceThree is greater than initial stockPriceShow (priceThree stockValue – initial stockValue; if the result is positive then it is a profit, else loss)
▪ Loss: If stockValue of priceThree is less than initial stockValue ▪ call printPriceChanges(ostream &output) ▪ You use iomanip functions, print stars and dashes in this function ▪ Check sample output for more details ▪ Special Conditions to consider: ▪ If the investor’s ID is invalid or stockPrice is negative or stockCount is negative, then show all the stock values with initial price, and other price changes to 0.00 ▪ You are allowed to declare local variables as needed.
• void writePriceChangesToFile(ostream &output) const writes the three price changes to investorsData.txt file. (Please check the objects declaration and function(s) calls in stocksMain.cpp to understand the flow) • double getInvestorPrice() const return initial stockPrice. [Think: How to get it? This is composition] • double getPriceOne() const return priceOne • double getPriceTwo() const return priceTwo • double getPriceThree() const return priceThree
• double getStockValue() const return stockValue Note: Following my suggestions on how to print stars and dashes are not mandatory. However, it is essential to match your output with the example output.
You can move those stars and dashes to any function according to your logic. Codegrade ignores whitespace. fileIO Class Implement the Derived class_2 named fileIO (Inheritance: is-a relationship) which is inherited from multiple classes investorType and stocksPortfolio through public access specifiers. This class has no member variables.
The fileIO UML class diagram is as follows: fileIO +unsigned int readWriteDataFile(ifstream &inFile, ofstream &outData) Function Descriptions: The following are more detailed descriptions of the required functions. • unsigned int readWriteDataFile(ifstream &inFile, ofstream &outData); This function does read and write operations on files.
Declare local variables as needed. It reads data from investorsData.txt file; declare objects of investorType and stocksPortfolio; call constructors or setters to set the parameters that are read from text file; Call the functions print(parameter) and calculateStockValue(parameter); These functions must write the investors’ portfolio (report) to investorsPortfolio.txt file similar to the output that is printed on Terminal. This function must print the total entries of investorsData.txt file that includes invalid data lines. Also, this function returns that total entries.
The investorType and stocksPortfolio classes must be fully completed prior to fileIO class. Refer to the example executions for formatting. Make sure your program includes the appropriate documentation. Your implementation files should be fully commented. Note: Even though you are not performing the calculations for invalid data, but when you write the investors data to investorsData.txt file, you have to pass the parameters exactly that are passed from stocksMain.cpp Don’t get confused with this: Initially, you use investorsData.txt as an outputFile, you write every investor’s data according to the parameters passed from stocksMain.cpp even though they are invalid.
You would be expecting 13 entries that includes valid and invalid data of investors’. After the declaration of fileIO fobj in stocksMain.cpp, investorsData.txt is considered as input text file. You must generate the investors’ portfolio report that is similar to the one printed on terminal. However, you will miss Error :- 318345 is invalid investorID for Dennis (messages for all invalid IDs) in investorsPortfolio.txt output file. The reason is stocksInvestor class has no ostream& variable for setters or print() functions.
Please observe that pattern carefully to fully understand the inheritance, composition, fileIO concepts. F ile s Provided : The following files are available to download for this assignment. • makefile. • stocksMain.cpp. • stockInvestor.h • investorType.h • stocksPortfolio.h • fileIO.h • CS202_Assignment3_Fall23 (Instruction pdf) • sample_output_on_terminal.txt • sample_investorsData.txt • sample_outputFile_investorPortfolios.txt Submission : Submit the following files only for this assignment. • stockInvestorImp.cpp • investorTypeImp.cpp • stocksPortfolioImp.cpp • fileIOImp.cpp How to Compile?
The provided make file assumes the source file names are as described. If you change the names, the make file will need to be edited. To build the given classes, one main provided and it has good and bad data. To compile, simply type: • make (Which will create the main for executables respectively.) How to Run your code? Use the following commands to run. • ./stocksMain Example: How the composition Works? From investorType class investorType(string id, string fName, string lName, string tyName, string stName, int stCount, double stPrice, ostream &output); Example: investorType fred(“T12345”, “Fred”, “Weasley”, “Trader”, “AAL”, 15, 35.78, cout); From stocksPortfolio class stocksPortfolio(double pOne, double pTwo, double pThree, investorType invTemp); Example: stocksPortfolio fredSP(37.89, 30.00, 25.66, fred); From the stocksPortfolio parameters, if you observe fred (object of investorType) is passed in fredSP (object of stocksPortfolio).
The other parameters should be initialized with priceOne, priceTwo, priceThree in the constructor body accordingly. In composition, only the object of investorType can access to investorType member functions. investorType fred(“T12345”, “Fred”, “Weasley”, “Trader”, “AAL”, 15, 35.78, cout); fred.print(cout); //prints the fred data fred.writeDataToFile(outFile, fred); //You write all the above parameter to //investorsData.txt exactly even if the given data is //invalid such as ID, negative stockCount, negative //stockPrice, stocksPortfolio fredSP(37.89, 30.00, 25.66, fred); fredSP.calculateStockValue(fred, cout); // calculate stock Value and print //(check sample output) fredSP.writePriceChangesToFile(outFile); //You write the priceChanges to //investorsData.txt file
Example Execution: (Note: I highlighted some example output in color to emphasize errors and the function calls needed to print that information) Your original text color for output should be black only. Below is an example program execution output for this Assignment.
Don’t make any changes in header files and stocksMain.cpp. Your code/logic is acceptable only in implementation files. Note: Below example execution format may have few extra white spaces on few pages. To show the output clean, I added a few white spaces in this example output. The codeGrade ignores the whitespace and so no need to be worried on that.
