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

Code

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

void print_binary(uint16_t val) {
    // Your logic here
    int bits = (val <= 0xFF) ? 8 : 16;

    // iteration from MSB to LSB and mask to distinguish between 8 or 16 bit value
    for (int i = bits - 1; i >= 0; i--) 
        putchar((val & (1 << i)) ? '1' : '0');  //putchar: function write single char. to standard output
    
}

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