[問題] enum
不好意思 一個的例子 想請問一下各位
底下 MAIN.CPP底線部份要如何設定才能正確的初始化？
應該說在類別裡面用列舉不是很懂 謝謝～
程式碼寫得應該不長 煩請指教一下
//main.cpp
#include"date.h"
#include<iostream>
int main()
{
Date today(11,_____________,2012);
std::cout << today.year() << '\n';
return 0;
}
//date.h
class Date{
public:
enum Month{jan=1, feb, mar, apr, may, jun, jul,
aug, sep, oct, nov, dec};
Date(int dd = 0, Month mm = Month(0), int yy = 0);
int day() const {return d;};
Month month() const {return m;};
int year() const {return y;};
static void set_default(int, Month, int);
private:
int d, y;
Month m;
static Date defalut_date;
};
//date.cpp
#include"date.h'
Date::Date(int dd, Month mm, int yy)
{
if(yy==0) y = default_date.year();
if(mm==0) m = default_date.month();
if(dd==0) d = default_date.day();
d = dd;
m = mm;
y = yy;
}
Date Date::defalut_date(1,dec,1990);
void Date::set_default(int d, Month m, int y)
{
Date::default_date = Date(d,m,y);
}
