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 bit = (val & 0xFF00) ? 15 : 7;
    for (;bit >= 0; bit--) {
        printf("%u", (val >> bit) & 1);
    }
}

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