Program/Source Code:

The source code to use the expression in the case statement is given below. The given program is compiled and executed successfully.

// Golang program to use the expression in the case statement.

package main
import "fmt"

func main() {
    var val int=3
    
     switch val{ 
       case 4-1: 
            fmt.Println("INDIA") 
       case 4-2: 
            fmt.Println("USA") 
       case 4-3: 
            fmt.Println("UK") 
       case 4-4: 
            fmt.Println("CHINA")
       default:  
            fmt.Println("Invalid value") 
   }  
}

Output:

INDIA

Explanation:

In the above program, we declare the package main. The main package is used to tell the Go language compiler that the package must be compiled and produced the executable file. Here, we imported the fmt package that includes the files of package fmt then we can use a function related to the fmt package.

In the main() function, we created a variable val, which is initialized with 3.

Here, we case 4-1: will be executed because variable val is initialized with 3. That's why the message "INDIA" will be printed on the console screen.
