Count Set Bits in an Integer

Code

#include <stdio.h>

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

    }
    return count;
}

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