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)

{
