为int *阵列[32]一个指向32整数数组或32个指针的数组为int？有关系吗？ [英] Is int *array[32] a pointer to an array of 32 ints, or an array of 32 pointers to int? Does it matter?

问题描述

如果我写

int *columns[32];

我在定义与32的指针数组 INT S'

或者是一个指向32数组 INT S'

我如何区分这两种？是否有区别？

How do I differentiate between the two? Is there a difference?

推荐答案

当有疑问 - 问 CDECL

$> cdecl 
Type `help' or `?' for help
cdecl> explain int *columns[32]
declare columns as array 32 of pointer to int

修改在回应评论：我发现CDECL源<一个href=\"http://www.google.com/$c$csearch/p?hl=en&sa=N&cd=2&ct=rc#4FSOSMZ6Pxc/distfiles/cdecl-2.5.tar.gz|cdecl-2.5/README&q=cdecl\"相对=nofollow>谷歌code搜索。它需要 GNU的readline 库。我认为它不应该编译它在Mac OS X或Windows的一个问题。

EDIT In response to comments: I found cdecl source on Google Code Search. It requires GNU readline library. I think it shouldn't be a problem to compile it on Mac OS X or Windows.
