Count Set Bits in an Integer

Code

#include <stdio.h>

int countSetBits(unsigned int n) {
    int count = 0;
    for (int i = 0; i<32; i++){
        if(n >> i & 1) {
            count++;
        }
    }
    return count;
}


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