C++全局重载operator =

Question

可能重复:
"operator =必须是非静态成员"是什么意思？(C++)

嗨,

我有以下代码......

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

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

gcc在编译时如何给我以下错误.

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

谢谢您的帮助.

您需要对自身进行重载=操作struct dataRecord.

就像是:

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