Summary

The C preprocessor and the C library are two important adjuncts to the C language. The C preprocessor, following preprocessor directives, adjusts your source code before it is compiled. The C library provides many functions designed to help with tasks such as input, output, file handling, memory management, sorting and searching, mathematical calculations, and string processing, to name a few. Reference Section V lists the complete ANSI C library.
