Answer 1

Answer:

What are Identifiers?

In C language identifiers are the names given to variables, constants, functions and user-define data. These identifier are defined against a set of rules.

Rules for an Identifier

An Identifier can only have alphanumeric characters(a-z , A-Z , 0-9) and underscore(_).

The first character of an identifier can only contain alphabet(a-z , A-Z) or underscore (_).

Identifiers are also case sensitive in C. For example name and Name are two different identifiers in C.

Keywords are not allowed to be used as Identifiers.

No special characters, such as semicolon, period, whitespaces, slash or comma are permitted to be used in or as Identifier.
