What are the key details of heap implementation in C++?

In C++, the heap is a region of memory used for dynamic memory allocation. You can allocate memory using 'new' and deallocate it with 'delete'. This allows for flexible memory management.

Can you explain how to allocate and deallocate memory on the heap?

Sure! To allocate memory on the heap, you use the 'new' operator, like this: int* ptr = new int;. To deallocate, use 'delete', like this: delete ptr;.

What happens if I forget to deallocate memory?

If you forget to deallocate memory, it leads to memory leaks, which can consume memory resources and potentially crash your program.

Are there any best practices for using heap memory in C++?

Yes, always pair 'new' with 'delete', consider using smart pointers like 'std::unique_ptr' or 'std::shared_ptr' to manage memory automatically.
