Go Multi-case switch Statement
The Multi-case switch Statement
It is possible to have multiple values for each case in the switch
statement:
Syntax
switch expression {
case x,y:
// code block if expression is evaluated to x or y
case v,w:
// code block if expression is evaluated to v or w
case z:
...
default:
// code block if expression is not found in any cases
}
case x,y:
// code block if expression is evaluated to x or y
case v,w:
// code block if expression is evaluated to v or w
case z:
...
default:
// code block if expression is not found in any cases
}
Multi-case switch Example
The example below uses the weekday number to return different text:
Example
package main
import "fmt"
func main() {
day := 5
switch day {
case 1,3,5:
fmt.Println("Odd weekday")
case 2,4:
fmt.Println("Even weekday")
case 6,7:
fmt.Println("Weekend")
default:
fmt.Println("Invalid day of day number")
}
}
import "fmt"
func main() {
day := 5
switch day {
case 1,3,5:
fmt.Println("Odd weekday")
case 2,4:
fmt.Println("Even weekday")
case 6,7:
fmt.Println("Weekend")
default:
fmt.Println("Invalid day of day number")
}
}
Result:
Odd weekday
