Dynamically allocated memory storage clarification

This question already has an answer here:

Stack Memory vs Heap Memory [duplicate] 3 answers

I thought I'd make this an answer:

Very simple:

If you use "new", the memory will be allocated from the heap.

"p" is a local variable. It's a pointer, and it's stored on the stack.

The 10,000 ints it points to were allocated by "new"; they're stored in the heap.

int* p = new int[100000];

Will always allocate memory from the heap (correct term is dynamic storage). That's implied using new or new[] .

Only the pointer variable itself will get static storage allocation outside of main() , local storage inside respectively.
