Keyword which is very new for you... am i right ?

Keywords are the reserved words used in programming. Each keywords has fixed meaning and that cannot be changed by user.

Keywords are defined by the Creators of that programming language.

Eg : int i;

Here "int" is a Keyword (Don't get confuse we will discuss it later)

Eg : Word "Good" from english... This will give same meaning in any sentense.

In the same way Keyword will give same logic in any program written by the Programmer (It's you, You are C Programmer).

Identifier ? (what I have to identify here ? oh no)

In C programming, identifiers are names given to C entities, such as variables, functions, structures etc.
