Program to take square root of a number.

Using Visual Studio 2015


==============================================================


#include<iostream>
using namespace std;
#include<conio.h>
#include<math.h>

void main()

float num;

cout<<"Enter number=";

cin>>num;

cout<<sqrt(num);

_getche();
}

It's a simple program to take a square root of a number. For this program we take an additional header file '#include<math.h>'. We take a special keyword for this too 'sqrt' and then enter the number in the brackets.
