What is a heap in C++?

What is a heap in C++?

A heap in C++ is a special area of memory used for dynamic memory allocation, where variables are allocated and freed in an arbitrary order.

How do I allocate memory on the heap?

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

What happens if I forget to free the memory?

If you forget to free the memory, it leads to a memory leak, which can cause your program to consume more memory over time.

Can you show me an example of using a heap in C++?

Sure! Here's a simple example:

int* arr = new int[10]; // allocate an array of 10 integers
// use the array
delete[] arr; // free the allocated memory
