一些学习c++的例题

#include <iostream>

using namespace std;

class CDate
{
private:
	int year, month, day;

public:
	void init_date(int y, int m, int d);
	void add_year(int y);
	void add_month(int m);
	void add_day(int d);
	void print(void);
};

void CDate::init_date(int y, int m, int d)
{   year = y; month = m; day = d; }

void CDate::add_year(int y) { year += y; }

void CDate::add_month(int m) { month += m; }

void CDate::add_day(int d) { day += d; }

void CDate::print(void)
{	cout << year << '-' << month << '-' << day << endl; }
