Count Set Bits in an Integer

Code

#include <stdio.h>

int countSetBits(unsigned int n) {
    unsigned char count = 0;
    for(int i = 31; i>=0;i--)
    {
        if((n>>i)&1)
        count++;
    }
    return count;
}

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