How does memory management work with arrays in C++?

In C++, arrays are a collection of elements stored in contiguous memory locations. When you declare an array, memory is allocated for it on the stack or heap depending on how you define it.

What’s the difference between stack and heap memory?

Stack memory is used for static memory allocation, while heap memory is used for dynamic memory allocation. Stack is faster but has limited size, whereas heap is larger but slower to access.

How do I dynamically allocate an array in C++?

You can use the new keyword to dynamically allocate an array. For example: int* arr = new int[size]; Remember to free the memory using delete[] arr;.

What happens if I forget to delete the dynamically allocated array?

If you forget to delete it, you'll create a memory leak, which can lead to increased memory usage and eventually exhaust available memory.
