13.21 CIST2362 Programming Assignment: Exploring the Vector Class Overview This programming assignment explores how the vector class works. The vector class you were introduced to behaves like an array. You used features like pushback(), popback(), size(), etc. In this programming assignment you will work with simplified version of the vector class that only holds integers. This class is named SimpleVectorOfInts. Your first task is to read and understand the SimpleVectorOfInts.h file. This is the interface for the class i.e. the contract with external software on the promised behavior. Then your main task is to implement each of the functions in the SimpleVectorOfInts.cpp file. As you implement each of the functions, you should test your functions by writing code in main. For example, once you finish the pushback() function, then you should test your pushback() in various scenarios in your main such as pushback() on an empty vector, pushback on a full vector, etc. The code in the main.cpp will not be uploaded for testing. The only code you will upload for testing is the SimpleVectorOfInts.h and SimpleVectorOfInts.cpp files. These two files will be evaluated using what are known as unit tests. A unit test is a test designed to check and verify a single piece of functionality. While all the tests are run at the same time, you should upload your files as you complete functions. The test will then let you know that you have passed testing for those functions. You will fail tests for unimplemented functions, but at least you can see the progress as you go. Note that you will be able to see the majority of the tests, but there will be some that are hidden. The purpose of this is to have you thoroughly test your code and try to satisfy the unexpected. This will help to sharpen your testing and programming skills. Requirements This SimpleVectorOfInts class is expected to behave like the standard vector class. There are a few requirements that need to be met: 1. The default capacity of the vector should be 10 elements, and the default size should be 0 . 2. When a push_back() is performed, the vector is increased by 5 if the vector is already full. 3. The pop_back() should change the size by 1, but should not affect the capacity. 4. The getElementAt() should ensure the subscript is within range, however, the [ operator should not. Submission Submit your SimpleVectorOfInts.h[cpp] 'for testing each time you think you have finished a function. Ensure that the tested functions are working before moving on. The sample template is setup using function stubs. This means they are empty functions that will compile, but will not produce the correct results. Therefore, you do not need to implement each stub before submitting
