Count Set Bits in an Integer

Code

#include <stdio.h>
#include <stdint.h>

int countSetBits(unsigned int n) {
    // Write your code here
    uint8_t count = 0;
    for (uint8_t i = 0; i < 32; i++)
    {
        if (n & (1 << i))
        {
            count += 1;
        }
    }
    return count;
}

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