 A C program is a sequence of text files (typically header and source files) that contain <DocLink src="/c/language/declarations">declarations</DocLink>. They undergo <DocLink src="/c/language/translation_phases">translation</DocLink> to become an executable program, which is executed when the OS calls its <DocLink src="/c/language/main_function">main function</DocLink> (unless it is itself the OS or another *freestanding* program, in which case the entry point is implementation-defined).
 
 Certain words in a C program have special meaning, they are <DocLink src="/c/keyword">keywords</DocLink>. Others can be used as <DocLink src="/c/language/identifier">identifiers</DocLink>, which may be used to identify <DocLink src="/c/language/object">objects</DocLink>, <DocLink src="/c/language/functions">functions</DocLink>, <DocLink src="/c/language/struct">struct</DocLink>, <DocLink src="/c/language/union">union</DocLink>, or <DocLink src="/c/language/enum">enumeration</DocLink> tags, their members, <DocLink src="/c/language/typedef">typedef</DocLink> names, <DocLink src="/c/language/statements">labels</DocLink>, or  <DocLink src="/c/preprocessor/replace">macros</DocLink>.
