BASIC ELEMENTS IN C

BASIC ELEMENTS IN C:

The C language is composed of the following basic types of elements:

constants, identifiers, operators, punctuation, and keywords

These elements are collectively known as tokens. A token is a source program text that the compiler does not break down into component elements.

Consider the statement:

number = number + 1;

The tokens are,

number	-	identifier (variable)
=	-	operator
+	-	operator
1	-	constant
;	-	punctuation

The above statement has a collection of tokens such as identifier, constant, operator etc. The words like if, while, for etc., are termed as keywords in C programming language and their usage is restricted to specific purposes.
