Working with Data Structures: Stack main.cpp

The code defines a simple program that utilizes a stack data structure. The functionality can be summarized as follows: 1. **Initialization**: A stack called `intStack` of integers is created with a maximum capacity defined by `MAX_ITEMS`, which is set to 5. 2. **Empty Stack Demonstration**: The stack is cleared using the `makeEmpty()` method, and it checks if the stack is empty by popping items (if any) and printing them. Initially, it will show "The contents of the cleared stack are: NULL". 3. **Input Loop**: The program prompts the user to enter integers to push onto the stack. It keeps accepting input until the stack reaches its maximum capacity (full). 4. **Display Stack Values**: After reaching full capacity, the program pops all items from the stack and displays them in the order they were added, ending with "NULL" to indicate the end of the stack. 5. **Return**: The program completes execution and returns 0, indicating successful termination. This code effectively demonstrates basic stack operations: pushing items onto the stack, checking if it's empty or full, and popping items off the stack.
