This section contains the Golang switch find output programs (set 2) with their output and explanations.
Program 1
package main
import "fmt"
func main() {
switch 30 {
case 11 to 20:
fmt.Println("Between 11 to 20")
case 21 to 30:
fmt.Println("Between 21 to 30")
case 31 to 40:
fmt.Println("Between 31 to 40")
case 41 to 50:
fmt.Println("Between 41 to 50")
default:
fmt.Println("INVALID VALUE")
}
}
Program 2:
package main
import "fmt"
func main() {
switch 30 {
case 10, 15, 20:
fmt.Println("Number 10, 15, 20")
case 25, 30, 35:
fmt.Println("Number 25, 30, 35")
case 40, 45, 50:
fmt.Println("Number 40, 45, 50")
default:
fmt.Println("INVALID VALUE")
}
}
Program 3:
package main
import "fmt"
func main() {
var num = 12
switch {
case num < 10:
fmt.Println("Less than 10")
case num < 20:
fmt.Println("Less than 20")
case num < 30:
fmt.Println("Less than 30")
default:
fmt.Println("INVALID VALUE")
}
}
Program 4:
package main
import "fmt"
func main() {
var num = 37
switch {
case num >= 11 && num <= 20:
fmt.Println("Between 11 to 20")
case num >= 21 && num <= 30:
fmt.Println("Between 21 to 30")
case num >= 31 && num <= 40:
fmt.Println("Between 31 to 40")
default:
fmt.Println("INVALID VALUE")
}
}
Program 5:
package main
import "fmt"
func main() {
var num = 37
switch {
case num >= 11 && num <= 20:
fmt.Println("Between 11 to 20")
case num >= 21 && num <= 30:
fmt.Println("Between 21 to 30")
case num >= 31 && num <= 40:
fmt.Println("Between 31 to 40")
}
}
Go programming
Answer Program 1:
Output:
Explanation:
The above program will generate syntax errors because we used "to" to compare a range in the switch block, which was not valid.
Answer Program 2:
Output:
Explanation:
In the above program, we created a switch block and defined 4 cases and one default case. Here "case 25, 30, 35" matched based on given value 30 and printed the "Number 25, 30, 35" on the console screen.
Answer Program 3:
Output:
Explanation:
In the above program, we created a switch block and defined 4 cases and one default case. Here, case num<20 matched based on the value of num that is 12 and printed the "Less than 20" on the console screen.
Answer Program 4:
Output:
Explanation:
In the above program, we created a switch block and defined 4 cases and one default case. Here, "case num>=31 && num<=40 :" matched based on the value of num that is 37 and printed the "Between 31 to 40" on the console screen.
Answer Program 5:
Output:
Explanation:
In the above program, we created a switch block and defined 4 cases and one default case. Here, "case num>=31 && num<=40 :" matched based on the value of num that is 37 and printed the "Between 31 to 40" on the console screen.
Note: In Golang default case is not mandatory.
