Tokens in C are the smallest individual elements of the C programming language that are meaningful to the compiler. They are the basic components of a C program and include keywords, identifiers, constants, strings, special symbols, and operators.

  • Keywords: These are pre-defined or reserved words in the C programming language that perform specific functions in a program. Examples of keywords in C include "if," "else," "for," and "while".

  • Identifiers: These are user-defined names used for naming variables, functions, and arrays. Identifiers consist of an arbitrarily long sequence of letters and digits with either a letter or the underscore (_) as the first character.

  • Constants: These are fixed values that cannot be altered during the execution of a program. C constants can be classified into two categories: primary constants and secondary constants.

  • Strings: These are groups of characters enclosed in double quotations and are used to represent text in a C program.

  • Special Symbols: These are symbols used in C that have a special meaning and cannot be used for other purposes. Examples of special symbols include brackets .

  • Operators: These are symbols used to perform operations on variables and values in a C program. Examples of operators in C include arithmetic operators (+, -, *, /), relational operators (>, <, ==), and logical operators (&&, ||) .
