Count Set Bits in an Integer

Code

#include <stdio.h>

int countSetBits(unsigned int n) {
    // Write your code here
    int setbits = 0;
    for (int i = 0; i < 32; i++)
    {
        int temp = (n >> i) & 1;
        if(temp) setbits++;
    }
    return setbits;
}

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