7.2系统分析方法 7.2.100A过程模型 面向对象分析需要将真实世界进行抽象,并加以描述。分析的目的是为了构造一个系统属性和系统行为的模型,该模型是根据对象和对象之间的关系、动态控制和功能转移来确定的。为此,OOA过程应该包含以下步骤:

10.1 Introduction 10.2 const (Constant) Objects and const Member Functions 10.3 Composition: Objects as Members of Classes 10.4 friend Functions and friend Classes 10.5 Using the this Pointer 10.6 Dynamic Memory Management with Operators new and delete 10.7 static Class Members 10.8 Data Abstraction and Information Hiding
