为以下结构分配了多少内存
struct bharath
{
int b;
char c;
浮动d;
}
以及如何？
how much memory is allocated for following structure
struct bharath
{
int b;
char c;
float d;
}
and how?

至少足以满足结构的总内存需求。
由于结构中的基本类型可能会有所不同从平台宽度
到平台和实现到实现（除了char，
课程）结构的大小也会有所不同。
你是如何做到的，或者如何在运行时分配内存？前者是
，只是为任何类型分配，真的。如果是后者，这很可能是具体的实施，至少基于我潜伏在这个新闻组中，
和我（差）的标准知识。

Enough to fit at least the total memory requirements of the struct.
Since the primitive types in the struct can vary in width from platform
to platform and implementation to implementation (except char, of
course) the size of the struct will also vary.
How do you do it, or how is memory allocated at runtime? The former is
just allocating for any type, really. If the latter, this is likely
implementation specific, at least based on my lurking in this newsgroup,
and my (poor) knowledge of the Standard.

无。这是一种类型，而不是一个对象。

None. It''s a type, not an object.

让int大小为4B然后分配将是？
i想知道有关填充或其他相关信息的信息/>
填充？
let the int size is 4B then the allocation will be?
i want to know the info regarding padding or some other else related
to padding?
