**Square Root of a number using sqrt() function**

**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 : :**

**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 .
