Chapter 5. Input and Output


We've seen how to do some input/output (I/O) to make some of the earlier exercises possible. Now we'll learn more about those operations by covering the 80% of the I/O you'll need for most programs. If you're familiar with the workings of standard input, output, and error streams, you're ahead of the game. If not, we'll get you caught up by the end of this chapter. For now, think of "standard input" as being "the keyboard" and "standard output" as being "the display screen."
