The Best of Both Worlds
The following example is a complete program that creates a deck of cards and shuffles it. The
purpose of the example is to show how the Tools.h++ template collections can be used in
conjunction with the Standard C++ Library. See your Standard C++ Library documentation for
more information on the features used in the example.
/* Note: This example requires the C++ Standard Library */
#include <iostream.h>

char suit;
bool operator==(const Card& c) const
{ return rank == c.rank && suit == c.suit; }

// print card: e.g. '3-C' = three of clubs, 'A-S' = ace of spades
friend ostream& operator<<(ostream& ostr, const Card& c)
{ return (ostr << c.rank << "-" << c.suit << " "); }
