@Shubhanshu 

in your 2nd statement i.e S2, 

are we allocating dynamic memory for a function call ? then why its not in heap but in stack ? 

function calls are stored in stack i agree but i am not getting its relationship with dynamic allocation i.e "new".

please explain.

I mean to say that, suppose u call a function fun() and inside it's body we have declaration.

int *p = new int(20);

So through this we have proved that stack allocation support pointers. And through:-

delete(p);

We showed that we can deallocate space at run time too.
