# Square Root of a number using sqrt() function

Write a C++ Program to find Square Root of a number using sqrt() function. Here’s simple program to find Root of a Number using sqrt() function in C++ Programming Language.

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

Here is source code of the C++ Program to find SquareRoot of a number using sqrt() function. The C++ program is successfully compiled and run(on Codeblocks) on a Windows system. The program output is also shown in below.

## SOURCE CODE : :

```/*  C++ Program to find Square  Root of a number using sqrt() function */

#include<iostream>
#include<math.h>

using namespace std;

int main()
{
float sq,n;

cout<<"Enter any positive number :: ";
cin>>n;

sq=sqrt(n);

cout<<"\nSquare  root of Entered Number [ "<<n<<" ] is :: "<<sq<<"\n";

return 0;
}```

### Output : :

```/*  C++ Program to find SquareRoot of a number using sqrt() function */

Enter any positive number :: 10000

Square root of Entered Number [ 10000 ] is :: 100

Process returned 0```

Above is the source code for C++ Program to find SquareRoot of a number using sqrt() function which is successfully compiled and run on Windows System.The Output of the program is shown above .
