Answer: Option B
#include<stdio.h>
int fun(); /* function prototype */

int(*p) () = fun;
(*p) ();
return 0;
}
int fun()

The compiler will not know that the function int fun() exists. So we have to
define the function prototype of int fun();
To overcome this error, see the below program
#include<stdio.h>
int fun(); /* function prototype */
int main()
{
int(*p) () = fun;
(*p) ();
return 0;
}
int fun()
{
printf("Placementadda\n");
return 0;
}
