In lectures we have discussed the use of templates to provide the compiler with blueprints for functions and classes. These are used by the compiler to produce code that implements functions and/or classes that are suitable for the type(s) to which you apply them in your program code. PROBLEM DESCRIPTION Your task in this Assignment is to modify your Assignment 1 code in the following ways:  Replace the Node and Linkedlist classes by class templates. Therefore, when an instance of Node is created, the syntax will be Node. That allows for a more generic code, eliminating the need for typedef.  Use an LStack class template as a wrapper class around LinkedList. LStack will use a LinkedList instance as a member variable. When instances of EToll are added to LStack, they will be stored in the member LinkedList using methods from LinkedList. Note that the implementation of LStack must comply with the public interface and logic of stacks (elements are added and removed from the top of the stack, and internal nodes are not visible). Moreover, removing instances of EToll from the stack, and printing it can only use methods from LStack (i.e. push(i), pop(), peek(), isEmpty()). That is, if you want to remove an item from the stack, you can’t simply call the method remove from LinkedList, as it would violate the logic of stacks. This constraint will help students understand the dynamics of stacks, and the fact that only the top (first) element is visible at any time. For SENG1120 students who want to be challenged more, there is an extra requirement, worth a bonus 2.0 marks:  Create a class TollStack that extends LStack via inheritance. TollStack will declare and implement all the methods that are specific to the toll application, leaving all the native functionality of a generic stack in LStack.  The only methods allowed in the LStack class are the ones that would not change if the data type changed (push(i), pop(), peek(), isEmpty(), +=). All other methods that require a specific implementation for the EToll application (remove(), count(), totalIncome(), <<, -=) should be declared and implemented in the TollStack class. NOTES ON MAKEFILES Two makefiles have been provided – depending on whether or not you are attempting the bonus task – therefore you will have to rename one of these to simply makefile in order to compile your program correctly. SUBMISSION NOTES Make sure your code works with the files supplied, and DO NOT change them. For marking, we will add the demo file to the project and compile everything using the makefile, together with your own files. If it does not compile or run, your mark will be zero. Your submission should be made using the Assignments section of the course Blackboard site. Incorrectly submitted assignments will not be marked. You should provide the .h and .cpp/.hpp files related to the LStack, LinkedList and Node classes (plus TollStack if you are doing the Bonus Task), and your selected makefile only, plus an assessment item coversheet. Also, if necessary, provide a readme.txt file containing instructions or comments for the marker. Each program file should have a proper header comment section including your name, course and student number; and your code should be properly documented. Remember that your code should compile and run correctly using Cygwin. There should be no segmentation faults or memory leaks during or after the execution of the program. Compress all your files into a single .zip file, using your student number as the filename. For example, if your student number is c9876543, you would name your submission: c9876543.zip If you have attempted the Bonus Requirement (or you are a 6120 student), please include a blank text file in the same folder as your source files, simply called Bonus.txt – this is to make it clear to the marker that you are attempting this. Submit by selecting the Assignment 1 link that will be found in the Assessment section on Blackboard. DO NOT USE RAR or any compression format other than ZIP. Late submissions are subject to the rules specified in the Course Outline. Finally, a completed Assignment Cover Sheet should accompany your submission, as well as any Adverse Circumstances documentation, should you have applied for and been granted Adverse Circumstances before your submission! This assignment is worth 10 marks of your final result for the course. Compiling and running your files together with the demo files provided should output the same result from Assignment 1. Note that in the demo files provided, the element (PNG890, Light Truck) was replaced by an element (UTW951, Light Truck), as it had the same licence as another vehicle and might cause confusion.
