| functions) provide a convenient way to perform formatted output. You |
| call <code>printf</code> with a <dfn>format string</dfn> or <dfn>template string</dfn> |
| that specifies how to format the values of the remaining arguments. |
| |
| <p>Unless your program is a filter that specifically performs line- or |
| character-oriented processing, using <code>printf</code> or one of the other |
| related functions described in this section is usually the easiest and |
| most concise way to perform output. These functions are especially |
| useful for printing error messages, tables of data, and the like. |
