I have a `class A` as mentioned below:-

```
class A{
     int iData;
};

```

I neither want to create member function nor inherit the above `class A` nor change the specifier of `iData`.

My doubts:-

* How to access `iData` of an object say `obj1` which is an instance of `class A`?
* How to change or manipulate the `iData` of an object `obj1`?

**Note**: Don't use `friend`.
