"面向对象编程与ANSI-C.pdf" 在编程领域,不同的编程技术和语言各有其特点和适用场景。面向对象编程(Object-Oriented Programming,OOP)是一种流行且强大的编程范式,它强调通过对象来组织代码,提高代码的复用性和可维护性。尽管在标题中提到的是使用ANSI-C实现面向对象编程,ANSI-C本身并不原生支持OOP特性,但开发者可以借助一些技巧模拟实现类似的功能。 C++、Eiffel、Oberon-2和Smalltalk等语言都是面向对象的语言,它们提供内置的机制来支持类、对象、继承、多态等概念。然而,即使没有这些特性,我们也可以使用像ANSI-C这样的过程式语言来实现面向对象的设计原则,比如封装、继承和多态,只是实现方式会更为复杂。 面向对象编程的核心思想是将数据和操作数据的方法封装在一起,形成对象。在C语言中,可以通过结构体(struct)来封装数据,通过函数指针或函数原型来模拟方法,以此达到类的概念。而继承可以通过包含或组合其他结构体来实现,多态则可以通过函数指针来实现动态绑定。 本书的目的是不偏不倚地探讨如何在ANSI-C中实践面向对象编程。它将介绍OOP的关键技术,如如何创建和管理对象,如何设计类,以及如何实现继承和多态性。通过这种方式,读者不仅可以了解OOP的基本概念,还能理解为什么这些技术有助于解决实际问题,特别是在项目之间的代码重用方面。 面向对象编程的一大优势是代码的模块化和抽象性,这使得代码更易于理解和维护。尽管早期的编程语言如C没有内置的OOP支持,但理解如何在C中实现OOP可以帮助程序员更好地理解和对比C与C++等现代语言之间的差异,进一步提升编程技能。 面向对象编程与ANSI-C的结合是一个深入理解OOP原理和C语言的好方法,无论你是经验丰富的C程序员还是想要了解C++和C之间差异的初学者,这本书都提供了宝贵的见解和实践经验。通过学习,你可以掌握如何在有限的工具集内实现面向对象的设计,从而提升自己的编程能力。

没有任何一种编程技术能解决所有问题; 没有任何一种编程语言只输出正确的结果; 没有任何一个程序员需要从零开始一个项目。 -----这三句似曾相识? 这是一本17年前的书,写的是用纯C来实现OOP。。。 亘古的C,永远的C。。。 关天C,我没有其它要说的了。 关于这个资源,还有一句:原书+源码,全在这儿 我希望10年后我还在读它,看它。。。 No programming technique solves all problems. No programming language produces only correct results. No programmer should start each project from scratch. Object-oriented programming is the current cure-all — although it has been around for much more then ten years. At the core, there is little more to it then finally applying the good programming principles which we have been taught for more then twenty years. C++ (Eiffel, Oberon-2, Smalltalk ... take your pick) is the New Language because it is object-oriented — although you need not use it that way if you do not want to (or know how to), and it turns out that you can do just as well with plain ANSI-C. Only object-orientation permits code reuse between projects — although the idea of subroutines is as old as computers and good programmers always carried their toolkits and libraries with them. This book is not going to praise object-oriented programming or condemn the Old Way. We are simply going to use ANSI-C to discover how object-oriented programming is done, what its techniques are, why they help us solve bigger problems, and how we harness generality and program to catch mistakes earlier. Along the way we encounter all the jargon — classes, inheritance, instances, linkage, methods, objects, polymorphisms, and more — but we take it out of the realm of magic and see how it translates into the things we have known and done all along. I had fun discovering that ANSI-C is a full-scale object-oriented language. To share this fun you need to be reasonably fluent in ANSI-C to begin with — feeling comfortable with structures, pointers, prototypes, and function pointers is a must. Working through the book you will encounter all the newspeak — according to Orwell and Webster a language ‘‘designed to diminish the range of thought’’ — and I will try to
