#include<stdio.h>
#include<conio.h>
main()
{
int n,p,r;
printf("entr the number\n");
scanf("%d",&n);
printf("enter the pos\n");
scanf("%d",&p);
r=(n&(1<<(p-1)));
if(r)
printf("bit is set");
else
printf("bit is not set");
getch();
}


if the question is check the bit if the bit is not set then
set that bit then we use the following code


#include<stdio.h>
#include<conio.h>
main()
{
int p,r;
static int n;
printf("entr the number\n");
scanf("%d",&n);
printf("enter the pos\n");
scanf("%d",&p);
r=(n&(1<<(p-1)));
if(r)
printf("bit is set");
else
{
printf("bit is not set");
n=n|(1<<p-1);
printf("number %d",n);
}
getch();
}
