An operator is a symbol that tells the compiler to perform specific mathematical or logical functions. C language is rich in built-in operators and provides the following types of operators:

Arithmetic Operators

Arithmetic Operators are used to performing mathematical calculations like addition +, subtraction -, multiplication *, division / and modulus %.

Operator Description
+ Addition
- Subtraction
* Multiplication
/ Division
% Modulus

Increment and Decrement Operators

Increment and Decrement Operators are useful operators generally used to minimize the calculation, i.e. ++x & x++ means x=x+1 or --x & x−− means x=x-1. But there is a slight difference between ++ or −− written before or after the operand. Applying the pre-increment first add one to the operand and then the result is assigned to the variable on left whereas post-increment first assigns the value to the variable on left and then increment the operand.

Relational Operators

Relational operators are used to compare two quantities or values.

Logical Operators

C provides three logical operators when we test more than one condition to make decisions. These are: && (meaning logical AND), || (meaning logical OR) and ! (meaning logical NOT).

Bitwise Operators

C provides a special operator for bit operation between two variables.

Assignment Operators

Assignment operators applied to assign the result of an expression to a variable. C has a collection of shorthand assignment operators.

Conditional Operator

C offers a ternary operator which is the conditional operator (?: in combination) to construct conditional expressions.

Special Operators

C supports some special operators
