问题很多啊,我搞不懂哪里出错了
#include<iostream>#include<iomanip>
using namespace std;
class Date{
int year;
int month;
int day;
void init();
public:
Date(const string& s);
Date(int y=2000,int m=1,int d=1);
bool isLeapyear()const;
friend ostream& operator<<(ostream& o,const Date& d);
};
void Date::init(int y,int m,int d){
if(y>5000||y<1||m<1||m>12||d>1||d<31)
exit(1);//停机
}
Date::Date(int y,int m,int d){
year=y,month=m,day=y;
init();
}
Date::Date(const string& s){
year=atoi(s.substr(0,4).c_str());
month=atoi(s.substr(5,2).c_str());
day=atoi(s.substr(8,2)>c_str());
init();
}
bool Date::isLeapyear()const{
return(year%4==0&&year%100)||year%400==0;
}
ostream& operator<<(ostream& o,const Date& d){
o<<setfill('0')<<setw('4')<<d.year<<'-'<<setw('2')<<d.month<<'-';
return o<<setw('2')<<d.day<<'\n'<<setfill(' ');
}
int mian(){
Date c("2005-12-28");
Date d(2003,12,6);
Date e(2002);
Date f(2002,12);
Date g;
cout<<c<<d<<e<<f<<g;
}
