C和只有C语言有一个标准的64位整数类型？ [英] C and only C language has a standard 64 bit integer type ?
问题描述
你好
我在这里读到只有C语言有一个标准的64位整数。
你能告诉我是什么原因这个 ？有什么特别的关于
C语言？
你能告诉我一些这种整数类型的引用吗？什么时候介绍？
介绍？
谢谢

Hello
I''ve read here that only C language has a standard 64bit integer.
Can you please tell me what are the reasons for this ? What is special about
C language ?
Can you please show me some references to this integer type ? When was it
introduced ?
Thank you

那不太好。整数类型没有固定的大小，它们只有
具有最小尺寸。并且碰巧C的类型为long long，其中
必须至少为64bit，而C ++不是。
你能告诉吗？我这是什么原因？
C ++语言标准基于C89标准，该标准没有长期和b $ b。无论是。包含新的
类型的C标准的新版本在C ++标准之后一年完成。
C语言有什么特别之处？
Hello
I''ve read here that only C language has a standard 64bit integer.
That''s not quite it. The integer types don''t have fixed sizes, they only
have minimum sizes. And it happens that C has the type "long long", which
is required to be at least 64bit, and C++ doesn''t.
Can you please tell me what are the reasons for this ?
The C++ language standard is based on the C89 standard, which doesn''t have
"long long" either. The new version of the C standard that contains the new
type was finished one year after the C++ standard.
What is special about C language ?
Can you please show me some references to this integer type ? When was it
introduced ?
符合C99标准。
In the C99 standard.

不，C已经定义了有符号和无符号的''long long''整数类型
，必须包含至少64位，但可能有更多。
但它不是只有C，只是不是C ++。例如，Java就像其他一些语言那样具有完全宽度的64位整数类型。
你能告诉我这是什么原因吗？关于
C语言有什么特别之处？
Hello
I''ve read here that only C language has a standard 64bit integer.
No, C has defined the signed and unsigned ''long long'' integer types
that must contain at least 64 bits, but could have more.
But it is not "only C", just merely not C++. Java, for example, has
exact-width 64-bit integer types, as do some other languages.
Can you please tell me what are the reasons for this ? What is special about
C language ?
大部分关于C的特殊事情都没有什么可做的
有了这个。
至于原因，今天的磁盘驱动器成本低于
Most of the things that are special about C have nothing at all to do
with this.
As for the reasons, disk drives today cost less than
