Keywords are predefined, reserved words used in programming that have special meanings to the compiler. Keywords are part of the syntax and they cannot be used as an identifier.
-For example:
List Of All C Keywords
C Identifiers
Identifier refers to name given to entities such as variables, functions, structures etc.
Identifiers must be unique. They are created to give a unique name to an entity to identify it during the execution of the program.
For example:
' int ' is a Keyword 'Listed on Chart '
' money' is a Identifier || Name of a Variable
