#include<iostream>           // iostream, not iostream.h

using namespace std;         // ahem - not everyone's gonna like this

class numbers

   numbers num;
   num.readnumbers();
   num.add();
// getch();                  
} 

Enter the value of a: 1
Enter the value of b: 2
Addition: 3

WHEN I REPLACE <iostream>
AND REPLACED using namespace std; INSTEAD <conio.h> then following errors are coming
1)UNABLE TO OPEN INCLUDE FILE 'IOSTREAM' THIS ERROR IS COMING
2)DECLARATION SYNTAX ERROR
3)UNDEFINED SYMBOL 'COUT
4)UNDEFINED SYMBOL 'CIN

@p01ajanikar I'm guessing you are using Turbo C++ 3,0, is that the case?
I understand that some education courses still use it - but bear in mind that it is well over 20 years old and bears no resemblance to modern standardised C++.

[p01ajanikar]

Yes, I'm using Turbo 3.2 for educational purpose, so what should I need for practice?

[Chervil]

If you have a choice, and are not constrained by college rules or something, use one of code::blocks or Visual Studio Express.
