Program Listing

//  Check if any number is dividable by 16 without using / and %
//  operators.

#include <iostream>
#include <iomanip>

bool is_divisible_by_16(int num)
    if (num < 0)
        num = -num;

    while (num > 0)
        num -= 16;
        if (num == 0)
            return true;
        else if (num < 0)
            return false;
    return true;

int main()
    for (int i = 0; i <= 40; ++i)
        std::cout << std::boolalpha  << i  << " is divisble by 16: " << is_divisible_by_16(i) << "\n";
