C Programming – HackerRank Solution | Set Bits 3 |

(HackerRank) Write a Modular C Programming code to solve Set Bits 3, Find the number of set bits (number of 1’s) in binary representation of a given positive number.

Find the number of set bits (number of 1’s) in binary representation of a given positive number.

Input Format

First Line contains a positive integer ‘N’

Constraints

N>0 and N<=(2^31 -1)

Output Format

Output the number of set bits in a single line.

Sample Input 0

-3

Sample Output 0

Invalid

Sample Input 1

9

Sample Output 1

2

Explanation 1

 9 in binary is 1001 and number of 1's in 1001 is 2.

CODE:

#include<stdio.h>
#include<stdlib.h>
#include<string.h>
#include<math.h>

int main() {
    int bset=0,i=0;
    int n,r;
    scanf("%d",&n);
    if(n>0)
    {
    while(n!=0)
    {
        r=n%2;
        if(r==1)
           bset++;
        n=n/2;
        i++;
    }
    printf("%d",bset);
}
    else{
