Function

A function is a self contained block of statement that performs a coherent task of some kind.

Functions provides modularity to the software.

#include<stdio.h>
int add (int x, int y)
int z;
z = x + y;
return (z);
}
main( )
{
int i,j,k;
i = 10;
j = 20;
k = add(i,j)        /* function call */
printf("The value of k is %d\n",k);
}

Output:-
  The value of k is 30.
