Count Set Bits in an Integer

Code

#include <stdio.h>

int countSetBits(unsigned int n) {

    int counter =0;
    for(int i=0; i<32;i++)
    {
        if(n&(1<<i))
        counter++;
    }
    return counter;
}

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