Print Binary Representation of an 8-bit or 16-bit Value

Code

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

void print_binary(uint16_t val) {
    int i = 0;
    if(val <= 255)
        i = 7;
    else
        i = 15;
    while(i >= 0){
        printf("%u", val >> i & 1U);
        i--;
    }
}

int main() {
    uint16_t val;
    scanf("%hu", &val);
    print_binary(val);
    return 0;
}
