  Notes:
    short is (almost always) a 16 bit integer.
    This program assumes 16 bit integers.

#include <stdio.h>

main() {
  short a = 5;

/*  65535 is the two's complement representation of -1 in 16 bits */
  short b = -1;

  short c = a + b;
  printf ("%d%s%d%s%d\n",a, " + ", b, " = ", c);
}


/*  Program output
5 + -1  = 4
