Chapter 15. Strings

There was a time (long, long ago, when the earth was still molten and I was in high school) when people thought of computers as manipulating numeric values exclusively. Among the first use of computers was to calculate missile trajectories during World War II, and for a very long time, programming was taught in the math department of major universities.

Today, most programs are concerned more with manipulating and displaying strings of characters than with strings of numbers. Typically, these strings are used for word processing, document manipulation, and creation of web pages.
