如何删除VS警告C4091：'typedef'：当没有声明变量时，忽略'SPREADSHEET'左侧的 [英] How can I remove the VS warning C4091: 'typedef ' : ignored on left of 'SPREADSHEET' when no variable is declared

问题描述

此警告在我的代码中通过同一声明多次触发，其内容如下：

This warning is triggered multiple times in my code by the same declaration, which reads :

// Spreadsheet structure
typedef struct SPREADSHEET
{    
      int ID;               // ID of the spreadsheet    
      UINT nLines;          // Number of lines

      void CopyFrom(const SPREADSHEET* src)
      {
           ID = src->ID;
           nLines = src->nLines;
      }
};

我不想只是关闭该警告，

I don't want to just turn off that warning,

但是改变代码，使警告不会出现！

but rather change the code so that the warning doesn't come up !

注意：我不想在这里声明任何变量一个头文件），只定义结构'SPREADSHEET'应该包括...

NOTE : I don't want to declare any variables here (it's a header file), only define what the struct 'SPREADSHEET' should include...

推荐答案

删除 typedef 。它是C语言的结构体，C ++会自动为你。

Delete typedef. It's the C way of declaring structs, C++ does it automatically for you.
