Keywords are reserved words in the C programming language that have predefined meanings and cannot be used as identifiers (variable names, function names, etc.). Here are the 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
These keywords are part of the C language syntax and serve specific purposes. It’s important to note that keywords are case-sensitive, so they must be written exactly as shown above to be recognized by the C compiler.
