Go programming Language switch case
Go Programming Language switch case
switch case is another one of the approach to build the decision in go programming.
Syntax:
switch option {
case option1:
// task1
case option2:
//task2
default:
//task n
}
Go Language switch case Example
Below code illustrates the switch case decision blocks in Go programming.
package main
import "fmt"
func main() {
// declare variables
var option int
fmt.Print("Enter option: ")
fmt.Scanf("%d", &option)
fmt.Println("Go switch case")
switch option {
case 1:
fmt.Println("Option 1 is entered!")
case 2:
fmt.Println("Option 2 is entered!")
case 5:
fmt.Println("Option 5 is entered!")
default:
fmt.Println("Unknown option is entered!")
}
}
Output:
$ go build switch-case.go $ ./switch-case Enter option: 2 Go switch case Option 2 is entered! $ ./switch-case Enter option: 5 Go switch case Option 5 is entered! $ ./switch-case Enter option: 3 Go switch case Unknown option is entered!« Previous Next »
