为什么错啊？

[taylorwc]

#include <iostream>
#include <afx.h>
using namespace std;

void main()
{
void operator<<(ostream & os,const CTime & t)
{
os<<t.hour<<" hours,"<<t.minutes<<" minutes.";
}
CTime theTime = CTime::GetCurrentTime();
cout<<theTime;

}

不能在函数体内(包括main函数)内定义一个函数,

void operator<<(ostream & os,const CTime & t)
{
os<<t.hour<<" hours,"<<t.minutes<<" minutes.";
}

int main() {
CTime theTime = CTime::GetCurrentTime();
cout<<theTime;
return 0;
}

你重载<<不是很有问题吗？

[yuanhen]

就是函数外也是不可以的

[chinajiji]

ostream& operator<<(ostream & os,const CTime & t)
{
return os<<t.hour<<" hours,"<<t.minutes<<" minutes.";
}

int main() {
CTime theTime = CTime::GetCurrentTime();
cout<<theTime;
return 0;
}

为什么要这样的呢?解释下,谢谢.

yuanhen(Thinkpad T40 头坑王):
不定义这个operator<<了行不行?
再不行,我就格式化硬盘,看行不行,哈哈.

[chinajiji]

return os<<t.hour<<" hours,"<<t.minutes<<" minutes.";
这句加个return是为了打连发机关枪,如:

cout << theTime1 << theTime2 << endl;

[chinajiji]

t.hour是不是私有member?我没用过CTime,如果是,这样改:

return os<<t.GetHour()<<" hours,"<<t.GetMinutes()<<" minutes.";
