这个程序应该没问题吧.怎么通不过编译？
王高手指点！

using namespace std;
加上这句

加了后还是出现一大队错误。
真不知该怎么改.
望指点

没这么多吧

[此贴子已经被作者于2007-1-3 13:12:35编辑过]

我也不知道

呵呵，也是新手吧，都会犯同样的错误，我也经常犯呢：
你的类名后面多了个括号，你把他当函数来使用了！~
去掉后就OK了！~

哈哈，有人没看出来~~

[CODE]#include <iostream>
using namespace std;

class Location
{
public:
Location(int xx=0,int yy=0);
Location(Location & p);
~Location();
int GetX(){return X;}
int GetY(){return Y;}
private:
int X,Y;
};
Location::Location(int xx,int yy)
{
X=xx;
Y=yy;
cout<<"constructor Object.\n";
}
Location::~Location()
{
cout<<X<<","<<Y<<"objiect destroyed."<<endl;
}
Location::Location(Location & p)
{
X=p.X;
Y=p.Y;
cout<<"copy constructor called.\n";
}
void f(Location p)
{
cout<<"Function"<<p.GetX()<<","<<p.GetY()<<endl;
}

int main()
{
Location B(1,2);
f(B);

return 0;
}

[/CODE]

class Location()
哪有这个括号，去掉。
#include "stdio.h"
这个也多余，去掉
ok
