# C# operators Edit

## Introduction

C# provides a number of operators. Many of them are supported by the built-in types and allow you to perform basic operations with values of those types. Those operators include the following groups:

-**Arithmetic operators**

-**Relational operators**

-**Comparison operators **

-**Boolean logical operators **

-**Bitwise and shift operators **

-**Assignment operator **

## Arithmetic Operators

Operator | Description | Example |
---|---|---|

Adds two operands | A B = 30 | |

- | Subtracts second operand from the first | A - B = -10 |

* | Multiplies both operands | A * B = 200 |

/ | Divides numerator by de-numerator | B / A = 2 |

% | Modulus Operator and remainder of after an integer division | B % A = 0 |

Increment operator increases integer value by one | A = 11 | |

-- | Decrement operator decreases integer value by one | A-- = 9 |

## Relational Operators

Operator | Description | Example |
---|---|---|

== | Checks if the values of two operands are equal or not, if yes then condition becomes true. | (A == B) is not true. |

!= | Checks if the values of two operands are equal or not, if values are not equal then condition becomes true. | (A != B) is true. |

> | Checks if the value of left operand is greater than the value of right operand, if yes then condition becomes true. | (A > B) is not true. |

< | Checks if the value of left operand is less than the value of right operand, if yes then condition becomes true. | (A < B) is true. |

>= | Checks if the value of left operand is greater than or equal to the value of right operand, if yes then condition becomes true. | (A >= B) is not true. |

<= | Checks if the value of left operand is less than or equal to the value of right operand, if yes then condition becomes true. | (A <= B) is true. |

## Logical Operators

Operator | Description | Example |
---|---|---|

&& | Called Logical AND operator. If both the operands are non zero then condition becomes true. | (A && B) is false. |

|| | Called Logical OR Operator. If any of the two operands is non zero then condition becomes true. | (A || B) is true. |

! | Called Logical NOT Operator. Use to reverses the logical state of its operand. If a condition is true then Logical NOT operator will make false. | !(A && B) is true. |

## Bitwise Operators

p | q | p & q | p | q | p ^ q |
---|---|---|---|---|

0 | 0 | 0 | 0 | 0 |

0 | 1 | 0 | 1 | 1 |

1 | 1 | 1 | 1 | 0 |

1 | 0 | 0 | 1 | 1 |

## Assignment Operators

Operator | Description | Example |
---|---|---|

= | Simple assignment operator, Assigns values from right side operands to left side operand | C = A B assigns value of A B into C |

= | Add AND assignment operator, It adds right operand to the left operand and assign the result to left operand | C = A is equivalent to C = C A |

-= | Subtract AND assignment operator, It subtracts right operand from the left operand and assign the result to left operand | C -= A is equivalent to C = C - A |

*= | Multiply AND assignment operator, It multiplies right operand with the left operand and assign the result to left operand | C *= A is equivalent to C = C * A |

/= | Divide AND assignment operator, It divides left operand with the right operand and assign the result to left operand | C /= A is equivalent to C = C / A |

%= | Modulus AND assignment operator, It takes modulus using two operands and assign the result to left operand | C %= A is equivalent to C = C % A |

<<= | Left shift AND assignment operator | C <<= 2 is same as C = C << 2 |

>>= | Right shift AND assignment operator | C >>= 2 is same as C = C >> 2 |

&= | Bitwise AND assignment operator | C &= 2 is same as C = C & 2 |

^= | bitwise exclusive OR and assignment operator | C ^= 2 is same as C = C ^ 2 |

|= | bitwise inclusive OR and assignment operator | C |= 2 is same as C = C | 2 |
