// Minimal program

#include <iostream>

using namespace std;

int main(int argc, char **argv)
{
   short x;             // Defines a signed short variable 
   unsigned short y;    // Defines an unsigned short variable 

   x = -1;              // x = 1111111111111111 (2s compl code for -1)
   y = x;               // y = 1111111111111111

   cout << "signed number x:   " << x << endl;   // Prints -1
   cout << "unsigned number y: " << y << endl;   // Prints 65535 (2^16 - 1)
