A keyword is a reserved word that has an inherent meaning to the compiler and thus cannot be used as an identifier within the language. Keywords often represent a language's possible reference values and statements. They are always written in lowercase, so in case-sensitive languages such as C versions of the same word that are not all lowercase can be used as identifiers.
Examples
Reference Values:
- double
- int
- char
- string
- enum
- void
Statements:
- break
- if / else
- for / foreach
- switch / case / default
- do / while
- return
