我想定义一个年份：int year;
然后:cin>>year;//1998
最后我想抽取世纪数以及年份数，该怎样做？
例如：在上面分别提取19世纪和98年。

int year,shiji,nianfen;
cin>>year;
shiji=year/100;
nianfen=year-shiji*100;
我也不知道对不对 我是这么想的 希望可以帮到你

LS okok!^_^

学着学着就糊涂了，原来这样```。
年份那也可以year%100;晕死。

还请教一下，下面错在哪？

#include <iostream>
#include <string>
using namespace std;

class Month
{
public:
Month(){};
Month(string month,int day,int year);
string getMonth()const;
int getDay()const;
int getYear()const;

private:
string TheMonth;
int TheDay,
TheYear;
};
Month::Month(string month,int day,int year)
{
string TheMonth=month;
int TheDay=day,
TheYear=year;
}

inline string Month::getMonth()const
{
if (TheMonth=="March")
return 1;
else if(TheMonth=="April")
return 2;
else if(TheMonth=="May")
return 3;
else if(TheMonth=="June")
return 4;
else if(TheMonth=="July")
return 5;
else if(TheMonth=="August")
return 6;
else if(TheMonth=="September")
return 7;
else if(TheMonth=="October")
return 8;
else if(TheMonth=="November")
return 9;
else if(TheMonth=="DeceMber")
return 10;
else if(TheMonth=="January")
return 11;
else if(TheMonth=="February")
return 12;
}

错误信息：error C2664: '__thiscall std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >::std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >(co

返回类型啊

return的int，怎么又string?
呵呵~

郁闷死了。太粗心了。
谢谢啦

很郁闷，又有点小问题了，帮忙找下 呵呵。

为什么我的驱动程序怎样改，最后结果都是：1

价格括号。。。year.YearMonthDay()

Month::getMonth()
最后加一个else return 0;
