Question

The return data-type of a function,whose prototype is declared in main(), is void.
It cointains an instruction return; as in

main()
{
    void create(int *p);
    *some code*
}
void create(node *list)
{
     *some code*
     return;
}

What will it return,and where will it return??

It’s not going to return anything, you might have return statements in a void function to kind of alter the flow and exit from the function. ie rather than:

void do_something(int i)
{
   if (i > 1) {
      /* do something */
   }
   /* otherwise do nothing */
}

you might have:

void do_something(int i)
{
   if (i <= 1)
      return;

   /* if haven't returned, do something */
}
