Programs and Classes: A Quick Example
A running C# program is a group of interacting type objects, most of which are instances of
classes. For example, suppose you have a program simulating a poker game. When it is run-
ning, it has an instance of a class called Dealer , whose job it is to run the game, and several
instances of a class called Player , which represent the players of the game.
The Dealer object stores such information as the current state of the card deck and the
number of players. Its actions include shuffling the deck and dealing the cards.
The Player class is very different. It stores such information as the player's name and the
amount of money left to bet, and performs such actions as analyzing the player's current hand
and placing bets. The running program is illustrated in Figure 4-1.
Figure 4-1. The objects in a running program
A real program would undoubtedly contain dozens of other classes besides Dealer and
Player . These would include classes such as Card and Deck . Each class models some thing that
is a component of the poker game.
■ Note A running program is a set of objects interacting with each other.
