C++ Program to Find Square Root of a Number

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.

Below I have shared a program to find square root in C++. If you have any problem then you can freely ask it by commenting below.

Program to Find Square Root of a Number in C++

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

using namespace std;

int main()
{
	float sq,n;
	cout<<"Enter any number:";
	cin>>n;
	sq=sqrt(n);
	cout<<"Square root of "<<n<<" is "<<sq;
	return 0;
}

Output:

Enter any number:9
Square root of 9 is 3
