# Square Root Program in C++

## 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

1. Declare a variable called `number` to store the number whose cube root you want to calculate.
2. Declare a variable called `root` to store the result of the cube root calculation.
3. Prompt the user to enter the number whose cube root they want to calculate, and store the input in the `number` variable.
4. Use the `sqrt()` function from the `math` library to calculate the cube root of the `number` and store the result in the `root` variable.
5. Print the result stored in the `root` variable to the console.

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;
}
``````

Output

``````Enter number whose root is to be found: 16
Square root of 16 is 4
``````
