这在C ++ AType（Ptr）[index]中意味着什么 [英] What does this mean in C++ AType(Ptr)[index]

问题描述

我想知道在C ++之前是否有人知道Pascal，也许你可以帮助我

out。我正在将一些pascal代码转换为C ++，我似乎无法理解AType（Ptr）[索引]试图完成的事情。任何帮助将

表示赞赏。谢谢。


类型

AType =数组[0 .. $ FF]的字节;


var Ptr ：指针;


移动（AType（Ptr）[index]，dest_word，2）;

I wonder if anyone here knew Pascal before C++, perhaps you could help me
out. I''m converting some pascal code into C++, and I can''t seem to
understand what AType(Ptr)[index] is trying to accomplish. Any helps would
be appreciated. Thanks.

type
AType = array[0..$FF] of byte;

var Ptr : Pointer;

Move(AType(Ptr)[index], dest_word, 2);

推荐答案
