Lab Objective: In this lab, students will create a C program that contains a calculation within a repetitious statement. They will compile and debug their program using Visual Studio 2015.
Software: Visual Studio 2015
Write a program that sums a sequence of integers. Assume that the first integer read with scanf () specifies the number of values remaining to be entered. Your program should read only one value each time scanf() is executed.
A typical input sequence might be 5 100 200 300 400 500
Use the below program template to answer each question. The program is created by answering all the questions hence, do not skip any question.
Programming Shell Template
1. Using the Xendesktop, open Visual Studio 2015. Create a new project and add a new .cpp file to the project. Type the programming shell template as stated up above and continue with the following steps below. Be sure to include comments throughout your program for readability purposes.
2. (Housekeeping): Declare the following variables in your program using appropriate data type. When selecting a data type keep in mind the type of value you want to store, i.e., int, float, character. Also, be sure to use conventional naming standards for all variable declarations.
(Hint): Since sum is going to be used for adding the value, it needs to be initialized to zero.
1. (Display Prompt): Write a printf() statement to ask user for the following message.
1. (Input):Add a scanf() statement to store user input for the number of values they wish to process.
2. (Loop structure):Now, you will write a loop structure to iterate for the number of values you want user to input.
To begin with, your loop structure will look like this –
1. Declare the following variable inside the loop to store the current value. Remember, the scope of this variable is limited to the loop only. It can’t be referred or used outside the loop.
2. (Output):Inside the loop, write a display prompt using a printf() statement for user to input a value using the following message.
1. (Input):Write a scanf() statement to store the value the user keys in from the keyboard into the variable named value.
2. (Assignment Statement):Here comes the main part of your program. Now, you need to add this value into the variable sum. So write an assignment statement to add the input value.
1. (Output):Outside of the loop, write a printf() statement to display the value of sum. Remember, the variable sum is declared outside of the loop so it can be referred/used anywhere within the main function. Also, to display the value stored in a variable you need to include a conversion specifier inside of the quotation marks in the printf() and the variable names within the parentheses.
2. (Output Screen) When you execute the program, it should be similar to the following:
