Tokens in C

Tokens are some of the most important elements used in the C language for creating a program. One can define tokens in C as the smallest individual elements in a program that is meaningful to the functioning of a compiler.

A token is the smallest unit used in a C program. Each and every punctuation and word that you come across in a C program is token. A compiler breaks a C program into tokens and then proceeds ahead to the next stages used in the compilation process.
