Operator | Meaning | Example | Result |
---|---|---|---|

+ | addition | 5+2 | 7 |

- | subtraction | 5-2 | 3 |

* | multiplication | 5x2 | 10 |

/ | division | 5/2 | 2 |

% | modulus operator to get remainder in integer division | 5 % 2 | 1 |

Operator | Meaning | Example | Result |
---|---|---|---|

< | less than | 5<2 | false |

> | greater than | 5>2 | true |

<= | less than or equal to | 5<=2 | false |

>= | greater than or equal to | 5>=2 | true |

== | equal to | 5==2 | false |

!= | not equal to | 5!==2 | true |

Operator | Meaning | Example | Result |
---|---|---|---|

&& | logical and | (5<2)&&(5>3) | false |

|| | logical or | (5<2)||(5>3) | true |

! | logical not (negation) | !(5<2) | true |

**Note** : logical **not**(!) is unary operator which requires only one operand (**true** to **false** and vice versa).

Increment operator (**++**) is used to increase the value of an integer or char variable.

Decrement operator (**--**) is used to reduce the value of an integer or char variable.

m = 15;

m++ **or** ++m will produce the result m = 16.

m = 15;

m-- **or** --m will produce the result m = 14.

**Note** : That m++ and m-- are referring the **post-fix** increment and decrement operation, and ++m and --m are referring the **prefix** increment and decrement operation.

Operator | Meaning | Example | Result |
---|---|---|---|

+= | m += 10 | m = m + 10 | 25 |

-= | m -= 10 | m = m - 10 | 5 |

*= | m *= 10 | m = m * 10 | 150 |

/= | m /= 10 | m = m / 10 | 1 |

%= | m %= 10 | m = m % 10 | 5 |

Conditional operator is used to check a condition and select a value depending on the condition. Normally the selected value will be assigned to a variable which ha the following form.
**variable = (condition) ? value 1 : value 2;**

When this operator is execute by the computer, the value of the condition is evaluated. If it is true then **value 1** is assigned to the variable, otherwise **value 2** is assigned to the variable.
Consider the following example.
**big = ( a > b ) ? a : b**

In this operation, the computer checks the value of the condition (a>b); If it is true **a** is assigned to **big**; otherwise **b** is **big**.

Conditional operator, like assignment operators, is also more concise and more efficient.

Operator | Meaning |
---|---|

<< | shifts the bits to left |

>> | shifts the bits to right |

~ | bitwise inversion (one's complement) |

& | bitwise logical and |

| | bitwise logical or |

^ | bitwise exclusive or |
