[問題] 關於=的多載..
以下是程式碼
#include <iostream>
#include <cstdlib>
using namespace std;
class CWin
{
private:
char id,*title;
public:
CWin(char i='D',char *text="default window"):id(i)
{
title=new char[50];
strcpy(title,text);
}
void set_data(char i,char *text)
{
id=i;
strcpy(title,text);
}
void show(void)
{
cout << "window" << id << ": " << title << endl;
}
~CWin(){delete[] title;}
CWin(const CWin &win)
{
id=win.id;
strcpy(title,win.title);
}
char get_id()
{
return this->id;
}
char get_title()
{
return this->title;
}
};
void operator=(CWin &w1,CWin &w2)
{
w1.get_id()=w2.get_id();
strcpy(w1.get_title(),w2.get_title());
return;
}
int main(void)
{
CWin win1('A',"main window");
CWin win2;
win1.show();
win2.show();
operator=(win1,win2);
win1.show();
system("pause");
return 0;
}
在這個程式碼裡,我嘗試著想要把operator=當成一般函式來寫~
但是卻無法編譯過,我想了很久不知道錯在哪邊
麻煩各位大大可以幫我看一下~謝謝!!
