A string is a group of characters, usually letters of the alphabet. In order to format your printout in such a way that it looks nice, has meaningful titles and names, and is esthetically pleasing to you and the people using the output of your program, you need the ability to output text data. Actually you have already been using strings, because the second program in this tutorial, way back in Chapter 2, output a message that was handled internally as a string. Acomplete definition is a series of "char" type data terminated by a NULL character, which is a zero.
When C is going to use a string of data in some way, either to compare it with another, output it, copy it to another string, or whatever, the functions are set up to do what they are called to do until a NULL, which is a zero, is detected.
