To print number of bit set in an number


// bit set
#include<stdio.h>
int main()
{
        int n,a,r,s;
        s=0;
        printf("enter the number:\n");
        scanf("%d",&n);
        while(n>=1)
        {
                r=n%2;
                n=n/2;
                printf("%d ",r);
                if(r==1)
                s=s+1;
        }
         printf("number of bit set is---->%d",s);
        return 0;
}
