Go Operators

Operators in Go are tools for performing operations on variables and values. For example, the + operator can be used to add two values together.

Example:

package main
import ("fmt")

func main() {
  var total = 11 + 8
  fmt.Println(total)
}

package main

import ("fmt")

​

func main() {

  var total = 11 + 8

  fmt.Println(total)

}

​

Output:

19

19

​

The + operator can also add a variable with a value or another variable:

Example:

package main
import ("fmt")

func main() {
  var (
    horsepower1 = 100 + 50      // 150
    horsepower2 = horsepower1 + 250 // 400
    totalHorsepower = horsepower2 + horsepower2 // 800
  )
  fmt.Println(totalHorsepower)
}

package main

import ("fmt")

​

func main() {

  var (

    horsepower1 = 100 + 50      // 150

    horsepower2 = horsepower1 + 250 // 400

    totalHorsepower = horsepower2 + horsepower2 // 800

  )

  fmt.Println(totalHorsepower)

}

​

Output:

800

800
