The simplest components or building pieces needed to create a C programme are known as tokens. Identifiers, Keywords, Constants, Operators, Special Characters, and Strings are the six different categories of C tokens.

DEFINITION OF TOKENS:

Tokens in C language are the smallest elements or the building blocks used to construct a C program.

TYPES :

There are five types of java tokens

• keywords
• identifiers
• literals
• operators 
• separators.

In the context of programming languages, particularly C and C++, a token is the smallest meaningful unit of a program. Tokens are the building blocks of source code and are used to represent various elements such as keywords, identifiers, literals, operators, and punctuation symbols.

In C, there are several types of tokens. Here are the most common types:

1. Keywords: These are reserved words that have a specific meaning in the C language. Examples include “if,” “else,” “for,” “while,” “int,” “float,” and so on.
2. Identifiers: These are user-defined names used to represent variables, functions, or other entities. An identifier must start with a letter (uppercase or lowercase) or an underscore and can be followed by a combination of letters, digits, or underscores.
3. Constants: Constants represent fixed values that do not change during the program’s execution. There are different types of constants in C, such as integer constants, floating-point constants, character constants, and string literals.
4. Operators: Operators perform various operations on operands. C supports a wide range of operators, including arithmetic operators (+, -, *, /), relational operators (>, <, ==), logical operators (&&, ||, !), assignment operators (=, +=, -=), and more.
5. Punctuation Symbols: These symbols are used to separate parts of the program and indicate the structure or syntax. Examples include parentheses (), braces {}, brackets [], commas ,, semicolons ;, and the period ..
6. Special Symbols: C also includes special symbols such as the hash (#) used for preprocessor directives, backslash () for escape sequences, and the question mark (?) for the conditional operator.

These are the main types of tokens in the C programming language. Understanding and correctly using these tokens is crucial for writing valid and meaningful C programs.
