Question #286 Difficulty: 2

According to the C++17 standard, what is the output of this program? 

    #include<iostream>

int main()
{
    unsigned short x=0xFFFF;
    unsigned short y=0xFFFF;
    auto z=x*y;
    std::cout << (z > 0);
}

Hint:

x and y both go through integer promotions before being multiplied, resulting in another type than short.
