Program/Source Code:

The source code to read the value of the integer variable is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

// Scala program to read the value of 
// integer variable

object Sample{  
    def main(args:Array[String]){  
        var num:Int=0
          
        print("Enter number: ")
        num = scala.io.StdIn.readInt()
        
        println("Entered number: "+num)
    }  
}

Output:

Enter number: 108
Entered number: 108

Explanation:

In the above program, we used an object-oriented approach to create the program. Here, we created an object Sample. We defined main() function. The main() function is the entry point for the program.

In the main() function, we created an integer variable num. Then we read the value of variable num using the scala.io.StdIn.readInt() function. After that, we printed the entered number on the console screen.
