Keywords

Keywords are the vocabulary of C. Because they are special to C, you can't use them for variable names. Many of these keywords specify various types, such as int. Others, such as if, are used to control the order in which program statements are executed. In the following list of C keywords, boldface indicates keywords added by the ANSI C standard, and italics indicate new keywords proposed by the C9X committee for the next version of the standard.
