北京理工大学面向对象程序设计第三次上机习题答案~
1. Define MyString class with demands as follows:
1.1 MyString can save any string
1.2 Overload operator+ to append string to another one
1.3 Define Find function to locate the position of searching a character
1.4 Define Mid function to get substring one string
1.5 The client can use MyString you define like as in the main:
void main()
{
MyString s1( China ), s2
s2 = Love
cout << I + s2+ s1
int pos = s1.Find( a ) // pos is 4, or zero if a is not found.
int a = 1, b = 3
MyString my = s2.Mid(a, b) // a represents starting position, b represents length. So Mid can get substring.
}
NOTE: The type, string in C++, is forbidden in your program.
2. Define InternetURL class to save a URL string like as www.bit.edu.cn ，and finish the demands as follows:
2.1 Use MyString you just finished before to save URL string；
2.2 Define member function getDomain (2016-06-01, Visual C++, 3KB, 下载13次)

企业内部的很多业务都可以抽象为一个或者若干个工作流，最典型的是收发文工作流。一个发文流程可能要经历起草，审批，校对，领导签字，传阅等步骤。传统的办公模式完成此流程需要投入很多人力，而且运转起来较慢，容易出错，如果采用办公自动化系统，公文的流转就可以自动化，显然有很多好处。
UML（Unified Modeling Language)是一种面向对象的建模语言，它已经广泛用于面向对象系统的分析和设计。统一过程(Unified Process)是一种软件工程方法，它将软件开发过程分为一系列的工作流程(Workflow)，充分发挥了迭代的开发思想，是软件开发成功的重要因素。
Struts是基于JAVA的一个开源项目，采用模块化的设计思想将业务逻辑，数据存储和用户界面分离，简化了企业级应用程序的构建。
