面向对象的代码，面向非面向对象的语言 [英] Object oriented code,in non-object oriented language

问题描述

这个语句是真的吗

编写面向对象的代码，即使是面向非面向对象的语言。

任何人都可以站点一个例子..或提供一些链接...

解决方案

是的，你可以这样做，你可以像c这样的过程语言模拟继承和多态性之类的OOP概念。

由于你要求一个代码示例，这里是一个：

要模拟继承，你需要的是结构的第一个成员是

  struct BaseClass 
 {
 // ... 
}; 
 struct DerivedClass 
 {
 struct BaseClass super; 
 // .... 
}; 
 
 struct DerivedClass d; 
 // UpCasting示例
 struct BaseClass * base_ptr =（struct BaseClass *）& d; 
 //下载示例
 struct DerivedClass * derived_ptr =（struct DerivedClass *）base_ptr; 
  

当然，如果你真的需要OOP，你应该使用OOP语言，而不是这样。 / p>

Is this statement true??

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

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

解决方案

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.
