What is heap usage in C++?

What is heap usage in C++?

Heap usage in C++ refers to the dynamic memory allocation that occurs in the heap segment of memory, allowing for flexible memory management.

How do I allocate memory on the heap?

You can allocate memory on the heap using the new operator. For example, int* ptr = new int; allocates memory for an integer.

What happens if I forget to free the memory?

Forgetting to free memory can lead to memory leaks, which can exhaust available memory and degrade performance over time.

How do I deallocate memory in C++?

You can deallocate memory using the delete operator. For example, delete ptr; frees the memory allocated for the integer.

Are there any best practices for heap memory management?

Yes, always ensure to pair new with delete, use smart pointers for automatic memory management, and avoid memory leaks.
