1. Keywords: Keywords are reserved words in C programming that have special meanings and cannot be used as identifiers. Examples of keywords in C include "int," "if," "else," "for," and "while."
2. Identifiers: Identifiers are user-defined names given to variables, functions, and other entities in a C program. Identifiers must start with a letter or underscore and can contain letters, digits, and underscores.
3. Constants: Constants are fixed values that do not change during the execution of a program. There are different types of constants in C, such as integer constants, floating-point constants, character constants, and string constants.
4. Operators: Operators are symbols used to perform operations on operands in C programming. Examples of operators in C include arithmetic operators (+, -, *, /), relational operators (==, !=, <, >), logical operators (&&, ||, !), and assignment operators (=, +=, -=).
5. Punctuation: Punctuation tokens in C programming include symbols such as commas (,), semicolons (;), parentheses (()), braces ({ }), and brackets ([]). These symbols are used to separate elements of a program, define control structures, and specify data types.

1. #define: The preprocessor directive #define is used to define preprocessor macros. It allows the programmer to assign a value or a string of characters to a symbolic name. The symbolic name can then be used in the program in place of the value or string it represents.
2. sizeof: The sizeof operator is used to determine the size in bytes of a data type or variable. It is a compile-time operator, which means that it is evaluated before the program is executed.
3. typedef: The typedef keyword is used to create a new data type that is an alias for an existing data type. This can be useful for making code more readable and maintainable.
4. volatile: The volatile keyword is used to indicate that a variable may be modified by external factors outside the program's control. This is useful for variables that interact with hardware devices or other external resources.
5. const: The const keyword is used to declare a constant variable. A constant variable cannot be modified once it has been initialized.
