为什么是“数组"?在 Visual-C++ 中标记为保留字? [英] Why is "array" marked as a reserved word in Visual-C++?

问题描述

Visual Studio 语法高亮显示该词为蓝色，就好像它是关键字或保留词一样.我尝试在网上搜索它，但是数组"这个词让搜索失败了，我得到的大部分页面都解释了什么是数组.有什么用?

解决方案

它不是 ISO 标准下的保留字.Microsoft 的 C++/CLI 定义了 array 在 cli 命名空间，Visual Studio 的语法高亮会将其视为保留字.这种用法将被视为供应商扩展，而不是任何国际 C 或 C++ 标准的一部分.

Visual Studio syntax highlighting colors this word blue as if it were a keyword or reserved word. I tried searching online for it but the word "array" throws the search off, I get mostly pages explaining what an array is. What is it used for?

解决方案

It's not a reserved word under ISO standards. Microsoft's C++/CLI defines array in the cli namespace, and Visual Studio's syntax highlighting will treat it as a reserved word. This usage would be considered a vendor extension and not a part of any international C or C++ standard.

ISO C99 Keywords:

break       extern      return      void
case        float       short       volatile
char        for         signed      while
const       goto        sizeof      _Bool
continue    if          static      _Complex
default     inline      struct      _Imaginary
do          int         switch
double      long        typedef
else        register    union
