填充和枚举 [英] padding and enums

问题描述

大家好，


数组保证在没有填充之前是连续的，或者在任何数组成员之后是

，但是enums怎么样？ ？

Hi all,

arrays are guaranteed to be contiguous with no padding before or
after any array member , but what about enums ..???

推荐答案

嗯，他们呢？


枚举类型与某些实现定义兼容

整数类型。该类型可能有填充位。那是你要求的吗？

Um, what about them?

An enumerated type is compatible with some implementation-defined
integral type. That type may have padding bits. Is that what you''re
asking?

我只是想清除这个概念结构的疑问吗？ >

I just wanted to clear the doubt that, whether the concept structure
padding also applies to enums ..???

整数类型兼容。 = A0该类型可能有填充位。 = A0是你问的问题？

关于数组的原始措辞不完全正确。

有可能在最后一个数组成员之后进行填充/>
a结构。例如：


struct foo {char bar [3]; int baz};


然后可以在bar [2]之后和baz之前填充。

枚举类型是一些整数类型（实现定义的），

因此适用于其他整体类型的规则同样适用。

Your original wording about arrays is not completely correct.
It is possible for there to be padding after the final array member in
a structure. For example:

struct foo { char bar[3]; int baz };

then there could be padding after bar[2] and before baz.
An enumeration type is some integral type (implementation-defined which),
so the same rules apply to it as apply to other integral types.
