# 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;
}
