# Go - Operators

Go - Operators compiler to perform specific mathematical or logical manipulations.

Go language is rich in built-in operators and provides the following types of operators- Arithmetic Operators
- Relational Operators
- Logical Operators
- Bitwise Operators
- Assignment Operators
- Miscellaneous Operators

## Arithmetic Operators

arithmetic operators supported by Go language. Assume variable A holds 15 and variable B holds 30 then

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

+ | Adds two operands | A + B gives 45 |

- | Subtracts second operand from the first | A - B gives -15 |

* | Multiplies both operands | A * B gives 450 |

/ | Divides the numerator by the denominator. | B / A gives 2 |

% | Modulus operator; gives the remainder after an integer division. | B % A gives 0 |

++ | Increment operator. It increases the integer value by one. | A++ gives 16 |

-- | Decrement operator. It decreases the integer value by one. | A-- gives 14 |

## Relational Operators

Assume variable A holds 10 and variable B holds 20, thenOperator | Description | Example |
---|---|---|

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

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

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

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

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

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

## Logical Operators

The following table lists all the logical operators supported by Go language. Assume variable A holds 1 and variable B holds 0, thenOperator | 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. |

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

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

|| | Called Logical OR Operator. If any of the two operands is true, then the 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 it false. | !(A && B) is true. |

## Bitwise Operators

There are following list of bitwise operator: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

There are following list of assignment operators.Operator | Description | Example |
---|---|---|

= | Simple assignment operator, Assigns values from right side operands to left side operand | C = A + B will assign 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 |
