日期和时间课程设计报告

1、.日期和时间课程设计报告1. 功能1.1课程设计题目功能：定义了日期类、时间类和日期时间综合类，重载了+、-、+、-、=、>=、<=、=、！=等运算符，可以设置时间、日期，比较时间和日期的大小，可以进行时间、日期对象的运算（加减），并按多种格式输出结果。1.2思想和方法：通过重载运算符使运算符实现对对象的加减运算，并在结果输出时自动载入闰年判断程序，实现结果的智能化输出；将菜单输出和结果输出隔开，防止混淆；日期类中将星期五单独定义，实现对错误的处理；通过拷贝函数的运用，实现“+”、“-”的重载。1.3增加的新功能：增加了对运算起始日期时间的修改和各操作菜单的退出功能。2. 详细设计

2、2.1 c_Time类：重载了+、-、+、-、=、！=、<、>、<=、>=运算符；将时间是否超过或少于当天设置为静态静态成员函数，设置了两个输出函数；“-”中，优化了结构，以四行将原程序代替，将少于一天的情况在后面列出；“+”中，将数值超过范围的情况的处理在后面列出。2.2 c_Date类：重载了+、-、+、-、=、！=、<、>、<=、>=运算符；设置了两个输出函数；简化了“+”运算符，同时修正了错误；“+”“-”中，将数值超过范围的情况的处理在后面列出；在第一个函数中，对当前时间日期进行了赋值，是起始日期时间的设定函数。2.3 TDmanage

3、类：重载了+、-、+、-、=、！=、<、>、<=、>=运算符；设置为c_Time和c_Date的派生类，可以实现对时间和日期的混合加减比较。2.4 TDglobal类：为输入输出的专门的类，重载了<<，>>运算符。2.5 error类：为专门处理错误的类，包括对原日期时间少于1900的处理，以及在“+”、“-”中结果少于1900的处理，以及输出时日期时间少于1900的处理。2.6 main类：以swith型进行菜单的输出，主要是对所有程序的综合处理，对菜单项的编辑，是最后的运行程序。3. 调试过程3.1出现了编译时无问题，而调试时提示没有相关函数

4、的问题，编译结束后载入相关文件解决了问题。3.2无法有效退出，将函数改为swith型解决问题。3.3出现了输出结果与预期不符的状况，更改了输出变量名解决问题。3.4最开始时没有设置对“+”的错误类进行设置，由于不太可能遇到相关情况，没有注意，后来看课本才发现。4. 输入输出开始界面时间格式的更改与否主操作菜单时间类操作，以“+”为例其后继续为主操作菜单日期类操作，以“-”为例综合类操作，以比较为例5. 总结本程序大量运用了运算符的重载，并且用到了多文件的处理，对以后处理或创建大程序很有帮助。而且运算符重载实际上是有很多技巧的，最一般的“+”“-”重载，需要考虑输入的数据的类型及对输出结果的要求

5、。另外错误处理也是个难关，即“error”类，不仅要考虑原日期时间的处理，还要考虑对运算符错误的处理，很有可能会落下某些情况，需要不断调试以保证每种情况都考虑到了。这个程序对个人对类处理必须相当熟悉，几乎将所有可能的情况都涉及了，而且难度不算太大，对于刚接触c+没有太长时间的我们是个很好的练习课程。6. 附件源程序：/cTime_t.h Begin#include <iostream.h>#include <time.h>#ifndef cTime_t_h#define cTime_t_hclass cTime_tstatic int FlagMoreDay;stati
