Data Types
C has four basic data types:
Char: This data type stores a single character. It can be signed or unsigned.
Int: This data type stores an integer. It can be signed or unsigned.
Float: This data type stores a floating-point number.
Double: This data type stores a double-precision floating-point number.

Operators
C has a variety of operators, including:
Arithmetic operators: These operators are used to perform arithmetic operations, such as addition, subtraction, multiplication, and division.
Relational operators: These operators are used to compare two values, such as equal to, not equal to, greater than, and less than.
Logical operators: These operators are used to combine two logical expressions, such as and, or, and not.
Bitwise operators: These operators are used to manipulate bits, such as and, or, and xor.
Assignment operators: These operators are used to assign a value to a variable.

Expressions
An expression is a combination of operators and operands. Operands can be variables, constants, or other expressions. Expressions are evaluated to produce a value.
