1、Visual C+课程设计报告 时间和日期电子工程与光电技术学院通信工程（1）班Xxx0904220xxx2010年4月一、 程序功能简介：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，进行时间、日期对象的运算，并输出多种格式的结果。二、 课程设计说明：1、 原程序日期类中输出星期几的函数有误，不能输出星期五，现修改如下：int cDate_t:GetDayOfWeek() /starting point : 1/1/1900 was Monday (Saturday=0,Sunday=1,.)
2、/1/1/1900是星期一，根据这个日期推断当前日期是星期几int weekday=2 ; /in 1/1/1900/从1/1/1900开始计算for(int TheYear=1900;TheYearYear;+TheYear) /loop to know the day in 1/1/this yearif(IsLeapYear(TheYear)weekday=(weekday+366)%7; elseweekday=(weekday+365)%7;/until here we found the correct day in 1/1/this yearfor(int TheMonth=1;
3、TheMonthMonth;+TheMonth)/年份计算完后，计算月份天数weekday=(weekday+GetDaysInMonth(TheMonth,Year)%7;/until here we found the correct day in 1/this monthif(weekday+Day)%7=0)return 6;elsereturn(weekday+Day)%7-1);/正确显示星期几/return (weekday+Day)%7-1;（修改前的，无法正确显示星期五） /the correct day in THIS day.2、根据要求在日期类中修改日期对象减去日期对象

12、inuteTemp;return ( cTime_t ( HourTemp,MinuteTemp,SecondTemp) );/return local class */4、修改综合类cTDmanage的结构，重新定义为日期类和时间类的派生类，并定义构造函数、各种运算符重载函数，重载输入输出函数：#ifndef TDmanage_h#define TDmanage_hclass cTDmanage:public cTime_t,public cDate_tpublic:cTDmanage ():cTime_t(),cDate_t()/构造函数cTDmanage (int year,int mo
