您最喜欢的C ++编译器是否支持64位整数类型？ [英] Does your favorite C++ compiler support 64-bit integer types?

问题描述

如果你赶时间，请跳到最后一段。


我的应用程序中的一些整数变量需要保持值

更大比2 ^ 32-1。


其他人不需要那么大。普通（读取：32位）微型计算机的时间和空间效率非常重要。


我想使用一些抽象层与C99的stdint.h相当，所以

我的变量声明指定位数。


我的应用程序是在通用硬件上运行在Linux，Mac，BSD和

Windows.


我对实际可移植性比ISO标准更感兴趣。

64位类型是长还是长也似乎无关紧要。


哪些C ++编译器能做什么，哪些没有64位整数类型？并且

他们有类似stdint.h的东西吗？

Please skip to the last paragraph if you are in a hurry.

Some of the integer variables in my application will need to hold values
bigger than 2^32-1.

Others won''t need to be that big. Time and space efficiencies on
run-of-the-mill (read: 32 bit) microcomputers are important.

I want to use some layer of abstraction comparable to C99''s stdint.h so
that my variable declarations specify the number of bits.

My app is to run on general-purpose hardware on Linux, Mac, BSD, and
Windows.

I am more interested in practical portability than in ISO standards.
Also it seems to be irrelevant whether the 64-bit type is long or long long.

Which C++ compilers do and which do not have 64-bit integer types? And
do they have something like stdint.h?

Digital Mars C ++ http://www.digitalmars.com

有long long。和stdint.h。

Digital Mars C++ http://www.digitalmars.com
has "long long" and stdint.h.

微软有一个64位数据类型，但我认为它比32位整数类型的效率低于b / b
。各种类型（除了通常的int等）在这里列出了

Microsofts has a 64 bit data type, though I think it is less efficient than
the 32 bit integer type. The various types (besides the usual int etc.) are
listed here.

它的长多是64位？

And its long long is 64 bits?
