30. Count Set Bits in an Integer

#include <stdio.h>
#include <cstdint>

int countSetBits(unsigned int n) {
    // Write your code herecp
    uint8_t count=0;
    for(uint8_t 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;
}
