C ++全局重载operator = [英] C++ globally overloaded operator=

问题描述

可能重复：

您好，

我有以下代码...

  //头文件
 struct dataRecord {
 size_t id; 
 char name [gcNameLength]; 
}; 
 
 void operator =（dataRecord& adr，const dataRecord& bdr）; 
  

编译时gcc给我出现以下错误。

 错误：'void operator =（dataRecord& const dataRecord&）'必须是非静态成员函数
  

感谢您的帮助。

解决方案

c $ c> = 操作

类似的操作：

  struct dataRecord {
 size_t id; 
 char name [gcNameLength]; 
 dataRecord& operator =（const dataRecord&）{
 //在这里写入重载代码
} 
};

What does “operator = must be a non-static member” mean? (C++)

Hi,

I have the following code...

// Header file
  struct dataRecord{
     size_t id;
     char name[gcNameLength];
  };

  void operator=(dataRecord &adr, const dataRecord &bdr);

How ever gcc gives me the following error when compiling.

error: ‘void operator=(dataRecord&, const dataRecord&)’ must be a nonstatic member function

Thanks for the help.

解决方案

You need to overload = operation on the struct dataRecord itself.

Something like:

struct dataRecord{
   size_t id;
   char name[gcNameLength];
   dataRecord& operator= (const dataRecord&) {
       // write overload code here
   }
};
