Count Set Bits in an Integer

Code

#include <stdio.h>

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

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