C++ Square root and Cube root of a given Number

Hello Everyone!

In this tutorial, we will learn how to find the Square root and Cube root of a given number by making use of the system defined functions sqrt() and cbrt() respectively, in the C++ programming language.

Code:

#include <iostream>
#include <cmath> // library which has predefined methods sqrt() and cbrt()

using namespace std;

int main()
{
    cout << "\n\nWelcome to Studytonight :-)\n\n\n";
    cout << " =====  Program to find the Square root and Cube root of a given number ===== \n\n";

    // variable declaration
    int n;
    // variable initialization and declaration
    double sq = 1, cb = 1;
    // taking input from the command line (user)
    cout << " \n\nEnter the number you want to find the Square root and Cube root of : ";
    cin >> n;
 
    // Finding the square root and the cube root using the system defined methods
    sq = sqrt(n);
    cb = cbrt(n);

    cout << " \n\nThe Square Root of the number " << n << " is : " << sq;
    cout << " \n\nThe Cube Root of the number " << n << " is : " << cb;
    cout << "\n\n\n";

    return 0;
}

Output:

C++ square root and cube root
