C++类的编写
第一步：写一个类文件命名：Tdates.h
class TDate
{
private:
int year,month,day;
public:
TDate(int y, int m, int d);
TDate();
void Print();
TDate operator+(TDate &c);
};
TDate::TDate(int y, int m, int d)
{
year = y;
month = m;
day = d;
}
TDate::TDate()
{
year = 0;
month = 0;
day = 0;
}
void TDate::Print()
{
cout<<"?ê??è??ú￡o"<<year<<"-"<<month<<"-"<<day<<endl;
}
TDate TDate::operator+(TDate &c)
{
TDate t ;
t.year = year + c.year;
t.month = month + c.month;
t.day = day + c.day;
return t;
}
第二步:
编写main函数：
#include<iostream>
using namespace std;
#include "TDates.h"
int main()
{
int i;
TDate d(2011,9,18), d1(2011,3,12), d2;
d2 = d + d1;
d.Print();
d2.Print();
return 0;
}
