c++nullptr

Where are these nullptr located?

int* x = nullptr;
class_example* obj = nullptr;

I understand what nullprt is, but where are these variables x and obj located?

Heap? or Stack?

Solution

  • Pointers are just ordinary variables, that happen to have values that are addresses of other objects (and those addresses could be on the heap).

    So in this snippet:

    int main() 
{
  int* x = nullptr;
  class_example* obj = nullptr;
}

    just like regular local variables, these pointers will be located on the stack.
