C++ Program to find Square Root of a number 

Problem

Write a program in C++ to find the square root of a number in C++.

Solution

To find the square root of a number in C++, you can use the sqrt() function.

The sqrt() function defined in the math.h header file can be used to calculate the square root in C++. This function takes a number as an argument and returns its square root.

Here’s a sample code snippet showing how you can find the square root of a number in C++ 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 = "<<sq;

    return 0;
}

Output
