 # cmake_demo

-## CMAKE
+#### 介绍
+{**以下是 Gitee 平台说明，您可以替换此简介**
+Gitee 是 OSCHINA 推出的基于 Git 的代码托管平台（同时支持 SVN）。专为开发者提供稳定、高效、安全的云端软件开发协作平台
+无论是个人、团队、或是企业，都能够用 Gitee 实现代码托管、项目管理、协作开发。企业项目请看 [https://gitee.com/enterprises](https://gitee.com/enterprises)}

-## 多态
-### 多态的本质
-同样的接口，可以即实现父类的功能，也可以实现子类的功能。主要看传参的类型。
+#### 软件架构
+软件架构说明

-C语言实现思路：
-因为语法不支持，因此采用特殊的方式来实现。
-| 类型 | 实现方式 | 弊端| 问题举例| 
-| --- | --- | --- | --- |
-| 匿名结构体 | 指针 | 多重继承，成员可能冲突 | B->A, C->A, D->B,D->C|
-| 虚函数表 | 指针 | 子类父类必须将虚表放在结构体最开头，且不支持多继承下的多态 | |
-| 虚函数多参数 | 指针 | 继承的父类无顺序强制要求，且可以多继承。但类方法参数变多。多继承需要人为注意是调用了其他类还是继承了其他类 | |
