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

Code

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

void print_binary(uint16_t val) {
    char arr[17]="0000000000000000";
    uint16_t tmp=val;
    int i=15;
    while(tmp > 0){
        arr[i]='0'+ (tmp%2);
        tmp/=2;
        i--;
    }
    if(val<=255) printf("%s",arr+8);
    else printf("%s",arr);
}

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