完成CTime时间类和CDate日期类的设计，使得主程序能够正确运行。 时间类CTime包含私有成员数据时（hour）分（minute）秒（second），均为int类型。 CDate日期类由CTime时间类公有派生而来，包含私有成员数据年（year）月（month）日（day），均为int类型。 main函数已给定，提交时只需要提交main函数外的代码部分。 #include<iostream> using namespace std; //你提交的代码在这里 int main() { int dy,dm,dd,th,tm,ts; cin>>dy>>dm>>dd>>th>>tm>>ts; CTime t1; cout<<"[T1]"; t1.Show(); CDate d1; cout<<"[D1]"; d1.Show(); CDate d2(dy,dm,dd); cout<<"[D2]"; d2.Show(); CDate d3(dy,dm,dd,th,tm,ts); cout<<"[D3]"; d3.Show(); CDate d4(dy,dm,dd,t1); cout<<"[D4]"; d4.Show(); CDate d5(t1); cout<<"[D5]"; d5.Show(); return 0; } Input 1行，包含6个整数，分别代表年，月，日，时，分和秒。 Output 输出包含4行，具体输出格式参照样例。 Sample Input 1 1949 10 1 16 28 37 Sample Output 1 Function #1 is called! [T1]9:10:11 Function #3 is called! Function #1 is called! Function #4 is called! [D1]2023-4-5 9:10:11 Function #3 is called! Function #9 is called! Function #1 is called! Function #5 is called! [D2]1949-10-1 9:10:11 Function #3 is called! Function #9 is called! Function #2 is called! Function #6 is called! [D3]1949-10-1 16:28:37 Function #3 is called! Function #9 is called! Function #0 is called! Function #7 is called! [D4]1949-10-1 9:10:11 Function #3 is called! Function #9 is called! Function #0 is called! Function #8 is called! [D5]2000-12-31 9:10:11 Function #3 is called! Function #9 is called!
