Keywords

In the C programming language, there are a set of reserved words called keywords that have predefined meanings and cannot be used as identifiers (variable or function names). These keywords are an integral part of the language syntax. Here is a list of keywords in C:

auto double int struct

break else long switch

case enum register typedef

char extern return union

const float short unsigned

continue for signed void

default goto sizeof volatile

do if static while

Note that these keywords are case-sensitive, meaning that you must use them exactly as shown above. Using any of these keywords as identifiers will result in a compilation error.
