What are the tokens in C?

Tokens in C are the smallest individual units of a program. They are categorized into six types:

1. Keywords: These are reserved words that have special meaning in C, such as int, float, if, else, for, while, etc.

2. Identifiers: These are the names given to different entities such as variables, functions, arrays, etc.

3. Constants: These are fixed values that do not change during the execution of a program, such as numbers, characters, and strings.

4. Strings: A string is a sequence of characters. In C, they are enclosed in double quotes.

5. Operators: These are symbols that perform certain operations on one or more operands. Examples include +, -, *, /, %, etc.

6. Special symbols: These are symbols used for specific purposes in C programming. Examples include brackets (), braces {}, semicolon ;, comma ,, etc.

7. Punctuators: These are symbols that separate different parts of a program. Examples include comma (,), semicolon (;), braces ({,}), etc.

Each token in C is separated by at least one space, tab, newline, or other whitespace characters.
