Tokens of C language

Tokens in C:

¾     C tokens are the basic buildings blocks in C language which are constructed together to write a C program.
¾     Each and every smallest individual units in a C program are known as C tokens.

     1.      Character sets
2.      Keywords
3.      Identifiers

6.      Operators

1. Character sets

¾     The character set of any programming language indicates the different characters the program can contain.

¾     Character set includes all the alphabets, digits and special symbols supported by the processor.

¾     Each of these special symbols may have some significance which will be discussed in the forthcoming chapters.
