**Square Root of Number program in C++**

**# Important Points:**

- Square root in C++ can be calculated using
**sqrt()**function defined in <**math.h>**header file. **sqrt()**function takes a number as an argument and returns the square root of that number.

**Example:**

Given number: 1296

Square root: 36

**# Algorithm**

- Create a variable
*number*and*root*. - Enter the number whose cube root is to be calculated.
- Get the cube root using function
*sqrt().*

**Code:**

```
#include<iostream>
#include<math.h>
using namespace std;
int main(){
float number, root;
cout << "Enter number whose root is to be found: ";
cin >> number;
root = sqrt(number);
cout << "Square root of " << number << " is " << root;
return 0;
}
```
