# Go - Arithmetic Operators

Advertisements

Following table shows all the arithmetic operators supported by Go language. Assume variable **A** holds 10 and variable **B** holds 20, then:

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

+ | Adds two operands | A + B gives 30 |

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

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

/ | 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 11 |

-- | Decrement operator. It decreases the integer value by one. | A-- gives 9 |

## Example

Try the following example to understand all the arithmetic operators available in Go programming language −

Live Demopackage main import "fmt" func main() { var a int = 21 var b int = 10 var c int c = a + b fmt.Printf("Line 1 - Value of c is %d\n", c ) c = a - b fmt.Printf("Line 2 - Value of c is %d\n", c ) c = a * b fmt.Printf("Line 3 - Value of c is %d\n", c ) c = a / b fmt.Printf("Line 4 - Value of c is %d\n", c ) c = a % b fmt.Printf("Line 5 - Value of c is %d\n", c ) a++ fmt.Printf("Line 6 - Value of a is %d\n", a ) a-- fmt.Printf("Line 7 - Value of a is %d\n", a ) }

When you compile and execute the above program, it produces the following result −

Line 1 - Value of c is 31 Line 2 - Value of c is 11 Line 3 - Value of c is 210 Line 4 - Value of c is 2 Line 5 - Value of c is 1 Line 6 - Value of a is 22 Line 7 - Value of a is 21
