Write a statement that computes the square root of a variable called discriminant

and stores the value in a variable called result.

// here is statement in C++ to compute square root of a variable.

double result=sqrt(discriminant);

Explanation:

Sqrt() method will compute the square root of a variable in C++.Read a value of discriminant and find the square root of it and assign it to variable "result".

Implementation in C++.

#include <bits/stdc++.h>

using namespace std;

// main function

int main()

{

  // variables

  double discriminant;

  // ask to enter discriminant

  cout<<"Enter the discriminant:";

  // read discriminant

  cin>>discriminant;

  double result=sqrt(discriminant);

  cout<<"Square root of discriminant is:"<<result<<endl;

  return 0;

}

Output:

Enter the discriminant:50                                                                                                  

Square root of discriminant is:7.07107
