Question

Is this statement true??

Writing object oriented code, even in non-object oriented language.

Can anybody site an example.. or provide some links…

Answer 1

Yes, you can do that, You can simulate OOP concepts like Inheritance and Polymorphism in a procedural language like c.

Since you ask for a Code Example, Here is one:

To simulate Inheritance all you need is the first member of a structure be an instance of the superclass, and then you can cast around pointers to base and derived classes just like C++ inheritance.

struct BaseClass 
{     
   //... 
};  
struct DerivedClass 
{     
   struct BaseClass super;     
   //....  
};  

struct DerivedClass d; 
//UpCasting example  
struct BaseClass *base_ptr = (struct BaseClass *)&d; 
//Downclasting Example 
struct DerivedClass *derived_ptr = (struct DerivedClass *)base_ptr; 

Ofcourse, If you really need OOP you should use a OOP language rather than playing around this way.
