// Create classes called Class1 and Class2 with each having one private member. Add member function to set a value (say setValue) on each class. Add one more function max() that is friendly to both classes, max() function should compare two private member of two classes and show maximum among them. Create one-one object of each class and set a value on them. Display the maximum number among them

```
#include <iostream>
