In this tutorial, you will learn about C keywords or reserve words that are parts of C syntax.
Keywords are reserved words that have special meaning to the compiler. Keywords cannot be used as an identifier name (variable name, constant name, etc). For example:
int count;
Here, int is a keyword that indicates that count is a variable of type int (integer).
C is a case-sensitive language. You need to specify all the keywords in lowercase in the program. C has 32 reserved words those are mentioned below.
