Hi Folks!!!!!
How can i define a pointer to a function with variable number of args..
However void pointer can hold the address of these functions , is there any other way of doing it …..
Ex: Declaration of a pointer to printf or scanf………..
Comments will be appreciated……

What’s the problem!!!!!

int  MyPrint( . . .  )
{
   cout<<" Inside MyPrint"<<endl;
}
int (*ptr2MyPrint ) ( . . . );

int main()
{
  ptr2MyPrint = Myprint;
  (ptr2Myprint) ( 2, 3, "Hi");
 (ptr2Myprint) ( "ImFine", 13, 3.65,"Hello");
 (ptr2Myprint) ( 2.78);
 
  return 0;
}

int MyPrint( . . . )

{

cout<<" Inside MyPrint"<<endl;

}

int (*ptr2MyPrint ) ( . . . );

int main()

{

ptr2MyPrint = Myprint;

(ptr2Myprint) ( 2, 3, "Hi");

(ptr2Myprint) ( "ImFine", 13, 3.65,"Hello");

(ptr2Myprint) ( 2.78);

return 0;

}

Why you are saying for void pointer. No logic to say here ” void pointer”. Only return type will be generic in case of void pointer.
