Chapter 1: Basic Input and Output: A Mini Adventure
Programming is not something you learn by reading. You learn programming only by writing programs. In this chapter, you get started by writing a simple (silly) adventure game. You also get the basic concepts behind programming in general and C# in particular. In addition to learning how C# is organized, you learn how to
∙Write the simplest interface for a C# console program.
∙Write data to the screen.
∙Get information from the user.
∙Create basic variables.
Project: The Mini Adventure
The game at the end of this chapter is simple but fun. Showing you the game in progress is easier than describing it, so take a look at Figures 1.1 and 1.2, which show the game in progress. The computer asks the user a few questions and then makes a silly story based on the user responses.
Figure 1.1: The game begins by asking the user a few questions.
Figure 1.2: The user’s answers result in a silly story.
You can see that the game asks the user questions and then incorporates the answers to create a silly story. This game probably won’t sell a million copies, but it’s quite impressive for a first
