# Operators in C

An expression consists of variables and constants separated by Operators in C. There are 7 types of Operators in C as listed below:

## 1. Arithmetic Operators:

Arithmetic Operators are used to perform arithmetic operations.

 Operator Meaning Example Result + addition 4+2 6 - subtraction 4-2 2 * multiplication 4*2 8 / division 4/2 2 % modulus 4%2 0

## 2. Relational Operators:

Relational Operators are used to compare the values of operands or expressions to produce a logical value. A logical is either true or false.

 Operator Meaning Example Result < less than 4<3 false > greater than 4>3 true <= less than or equal to 4<=3 false >= greater than or equal to 4>=3 true (==) equal to 4==3 false != not equal to 4!=3 true

## 3. Logical Operators:

Logical Operators are used to connect more relational operations to form a complex expression that is called Logical Operators or Logical expressions. A value obtained by evaluating a logical expression is always logical either true or false.

 Operator Meaning Example Result && logical and (4<3)&&(4>3) false || logical or (4<2) || (4>3) true ! logical not ! (4<2) true

## 4. Increment and Decrement operators (++ and – –):

The increment operator (++) is used to increase the value of an integer or char variable by 1. The decrement operator (- -) is used to reduce the value of an integer or char variable by 1.

Example:

`a = 25`

;

```a++ or ++a will produce the result a = 26
a = 25```

;

```a- - or - -a will produce the result a = 24

```

## 5. Assignment Operators:

Assignment Operators are used to perform arithmetic operations while assigning a value to a variable.

## 6. Conditional Operators or Ternary Operators (?:):

Conditional Operators are used to check a condition and select a value depending on the value of the condition. Normally the selected value will be assigned to a variable that has the following form :

`variable=(condition)?value1:value2;`

Example :

`big=(x>y)?x:y;`

## 7. Bitwise Operators:

Bitwise Operators are used to perform operations at a binary digit level. These operators are not commonly used and are used only in special applications where optimized use of storage is required.

 Operator Meaning << Shifts the bits to left >> Shifts the bit to right ~ Bitwise inversion & Bitwise logical and | Bitwise logical or ^ Bitwise exclusive or
