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 bits = (val <= 255) ? 8 : 16;

    for (int i = bits - 1; i >= 0; i--)
    {
        if (val & (1 << i))
        {
            putchar('1');
        }
        else
        {
            putchar('0');
        }
    }
    putchar('\n');
}

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