Answer 1

Does malloc allocate a block of memory on the heap or should it be called virtual adress space?

short answer: malloc allocates memory on the heap.

it's not precise enough to say that malloc allocates memory in the virtual adress[sic] space, since your call stack itself is part of that same space.
