代码：

#include <iostream>#include <iomanip>#include <string>using namespace std;typedef char string80[80];class Date{public: Date() {} Date(int y, int m, int d) { SetDate(y,m,d); } void SetDate(int y, int m, int d) { Year = y; Month = m; Day = d; } string80 &GetStringDate(string80 &Date) { sPRintf(Date, "%d/%d/%d", Year ,Month, Day); return Date; } protected: int Year, Month, Day;};class Time{public: Time() {} Time(int h, int m, int s) { SetTime(h,m,s); } void SetTime(int h, int m, int s) { Hours = h; Minutes = m; Second = s; } string80 &GetStringTime(string80 &Time) { sprintf(Time, "%d:%d:%d", Hours ,Minutes, Second); return Time; } protected: int Hours, Minutes, Second;};class TimeDate:public Date, public Time{public: TimeDate():Date() {} TimeDate(int y, int mo, int d, int h, int mi, int s):Date(y,mo,d),Time(h,mi,s) {} string80 & GetStringDT(string80 &DTstr) { sprintf(DTstr, "%d/%d/%d;%d:%d:%d",Year,Month,Day,Hours,Minutes,Second); return DTstr; }};int main (){ TimeDate dat1, dat2(2017,2,17,17,25,33); string80 DemoStr; dat1.SetDate(2017,1,17); dat1.SetTime(17,25,33); cout<<"The dat1 date is : "<<dat1.GetStringDate(DemoStr)<<endl; cout<<"The dat1 time is : "<<dat1.GetStringTime(DemoStr)<<endl; cout<<"The dat1 date and time is : "<<dat1.GetStringDT(DemoStr)<<endl; cout<<"the dat2 date and time is : "<<dat2.GetStringDT(DemoStr)<<endl; return 0;}
