Final answer:
Arrays on the stack are automatically managed in languages like C/C++. The memory for the array is allocated when the function begins, and freed once the function ends, eliminating the need for explicit cleanup.
Step-by-step explanation:
When working with arrays on the stack in languages like C or C++, memory management is handled automatically. The stack is a region of memory that stores temporary variables created by each function (including main). When a function declares an array on the stack, the space for that array is allocated at the beginning of the function's execution and is freed once the function returns. This means that you do not need to clean up explicitly; the array's memory will be reclaimed when the function that created it finishes. Since the stack operates on a Last In, First Out (LIFO) basis, the latest data pushed onto it will be the first to get popped off when no longer needed.
