Count Set Bits in an Integer

Code

#include <stdio.h>

int countSetBits(unsigned int n) {
    // Write your code here
    int co;
    for (int i=0; i<=31; i++){
        if (n&(1<<i)){
            co++;
        }
    }
    return co;
}

int main() {
    int n;
    scanf("%d", &n);
    printf("%d", countSetBits(n));
    return 0;
}
