Go - Arithmetic Operators

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 Demo 
package 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
