1、兴2成+锦程极计想告时间和日期电子工程与光电找术学院通信工程(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：intcDate_t:GetDayOfWeekO/startingpoint:1/1/1900wasMonday(Saturday=O,Sunday=I,.)1/1/1900是星期一，根据这个日期推断当前日期是星期几

2、intweekday=2;/in1/1/1900从1/1/1900开始计算for(intTheYear=1900;TheYearYear;+TheYear)/1ooptoknowthedayin1/1/thisyear(if(Is1eapYear(TheYear)weekday=(weekday+366)%7;e1seweekday=(weekday+365)%7;/unti1herewefoundthecorrectdayin1/1/thisyearfor(intTheMonth=I;TheMonthMonth;+TheMonth)/年份计算完后,计算月份天数weekday=(weekday

3、+GetDaysInMonth(TheMonth,Year)%7;/unti1herewefoundthecorrectdayin1/thismonthif(weekday+Day)%7=0)return6;e1sereturn(weekday+Day)%7T);正确显示星期几/return(Weekday+Day)%7T;(修改前的，无法正确显示星期五)thecorrectdayinTHISday.2、根据要求在日期类中修改日期对象减去日期对象的重载运算符-，使得结果不是另一个日期，而是天数：intcDate_t:operator-(cDate_t&D)重载-运算符修改为日期对象减去日期对象

4、，结果不是另一个日期对象，而是天数(intTempi,Temp2,NewDays=O;Temp1=GetDayOfYear(Year,Month,Day);Temp2=D.GetDayOfYear(D.Year,D.Month,D.Day);if(Year=D.Year)(NewDays=max(Tempi,Temp2)-min(Tempi,Temp2);e1sefor(intTemp3=min(Year,D.Year);Temp3D.Year)NewDays=NewDays+!emp1-Temp2;e1seNewDays=-(NewDays+Temp2-Temp1);returnNewDay

9、结果不是另一个时间对象，而是分钟数)(intnewhour,newminute;newhour=Hours-T.Hours;newminute=Minutes-T.Minutes;returnnewhour*60+newminute;/constcTime_tcTime_t:operator-(constcTime_t&T)const/operaor-function重载-运算符修改前的，结果为时间对象(intHourTemp,MinuteTemp,SecondTemp;/define3tempvariab1estogettimedata定义三个时间变量HourTemp=Hours-T.Hou

11、S秒数相减为负SecondTemp+=60;一MinuteTemp;)return(cTime_t(HourTemp,MinuteTemp,SecondTemp);/return1oca1c1ass*/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：#ifndefTDmanage_h#defineTDmanage_hc1asscTDmanage:pub1iecTime-t,pub1iccDate_t(pub1ic:cTDmanage():cTime_t(),cDate_t()构造函数(cTDmanage(intye
