   The following sample program simulates 1000 rolls of two six-sided
    dice.  It is written WITHOUT the use of classes.  Each die is
    represented by the function 'die()', which returns a value
    representing the result of a "roll".  Notice that the number of
    sides of each die is specified by the parameter passed to the
    'die()' function.
