34. Count Set Bits in an 8-bit Register

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

uint8_t count_set_bits(uint8_t reg) {
    // Your code 
    uint8_t count =0;
    for ( int i =0; i<8; i++)
    {
    count += (((reg >> i) & 0x01) ==1) ? (1) : (0);

    }
    return count;
}

int main() {
    uint8_t reg;
    scanf("%hhu", &reg);
    printf("%u", count_set_bits(reg));
    return 0;
