Count Set Bits in an 8-bit Register

Code

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

uint8_t count_set_bits(uint8_t reg) {
    // Your code here
    
    int count=0,i;
    for(i=0;i<8;i++){
        if(((reg>>i)&1)==1){
            count++;
        }
    }
    return count;

}

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