A function can itself stored in a memory address.By calling
the address ,instead of function name,we can invoke
function.
Eg.:
#include <stdio.h>
void sum(int,int);
{
void (*fp)(); //() denotes pointer to a function
fp=sum(); // no need & .reason : same of array
fp(10,20); //invoking function
}
void sum(int x,int y)
{
printf("sum of x%d and %d is =%d",x,y,x+y);
}
