#include<conio.h>

void prime ( int n);

void main ( )

{

int n;

printf (“enter a number”);

scanf (“%d”, & n);

prime ( n);

getch();

}

void prime ( int n)

{

int s = 0, i;

for ( i =2; i < = n /2; i ++)

{

if (n% i = = 0)

s++;

break;

}

if (s==0)

printf (“\n Given number is a prime number”);
