Write the code to input a number and print the square root. use the absolute value function to make sure that if the user enters a negative number

Code is in c++ and java.

Explanation:

C++ Code

#include <iostream>

#include <cmath>

using namespace std;

int main()

{

   float number;

   //input the value

   cout<<"Enter a number to get square root: ";

   cin>>number;

   // applying absolute to input number

number = abs(number);

   // calculate the square root

   float result = sqrt(number);

   cout<<"square root of "<<number<<" is = "<<result;

   cout<<endl;

   return 0;

}

Java Code

import java.util.Scanner;

public class SquareRoot {

   public static void main(String[] args){

       Scanner scanner = new Scanner(System.in);

       System.out.print("Enter a number to get square root:");

       double number = scanner.nextDouble();

       number = Math.abs(number);

       double result = Math.sqrt(number);

       System.out.println("square root of "+number+" is = "+result);

   }

}

Output

Case 1:

Enter a number to get square root: 9

square root of 9 is = 3

Case 2:

Enter a number to get square root: -9

square root of 9 is = 3
