源程序：
#include <iostream>
using namespace std;
class myDate
{
public:
myDate();
myDate(int,int,int);
void setDate(int,int,int);
void setDate(myDate);
myDate getDate();
void setYear(int);
int getMonth();
void printDate() const;
private:
int year, month, day;
};
//在类体外定义成员函数
myDate::myDate()
{
year = 1970;
month = 1;
day = 1;
}
myDate::myDate(int y, int m, int d)
{
year = y;
month = m;
day = d;
}
void myDate::setDate(int y, int m, int d)
{
year = y;
month = m;
day = d;
return;
}
void myDate::setDate(myDate oneD)
{
year = oneD.year;
month = oneD.month;
day = oneD.day;
return;
}
myDate myDate::getDate()
{
return *this;
}
void myDate::setYear(int y)
{
year = y;
return;
}
int myDate::getMonth()
{
return month;
}
void myDate::printDate() const
{
cout << year << "/" << month << "/" << day;
return;
}
int main()
{
myDate A;
myDate M;
myDate N(1995,8,30);
M.setDate(2001,12,23);
M.printDate();
cout << endl;
N.printDate();
cout << endl;
M.setDate(A);
A.printDate();
cout << endl;
system("pause");
return 0;
}
