Scala program to find the square root of a number

Program/Source Code:

The source code to find the square root of a number is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

// Scala program to find the 
// square root of a number

object Sample{  
    def main(args:Array[String]){  
        var num:Int    = 0;
        var res:Double = 0;
        
        print("Enter number: ")
        num=scala.io.StdIn.readInt()
        
        res = scala.math.sqrt(num)
        println("The square root is: "+res);
    }  
}

Output:

Enter number: 16
The square root is: 4.0

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 two variables num, res that are initialized with 0. Then we read the value of the num variable from the user and then we found the square root of the number using scala.math.sqrt() function. Here, scala.math is a package that contains the definition of sqrt() function.
