今天C ++的可移植性如何 [英] How portable is C++ today
问题描述
谈到代码可移植性，大多数人会认为C是比C ++更好的选择。这可能是5年或10年前的事，但今天怎么样？b $ b？还有很多平台或设备没有好的C ++编译器吗？ C ++提供了比C更多的东西，你会用它来构建一个新的跨平台项目，它将支持各种各样的b / b $ b平台，比如从手持设备到多节点服务器？

Hi,
When it comes to code portability, most people would think C is a better
choice then C++. That was probably true 5 or 10 years ago, but how
about today? Are there still many platforms or devices that have no
good C++ compiler? C++ offers a lot more then C, would you use it to
build a new cross-platform project that will support a wide range of
platforms, say from handheld devices to multi-nodes servers?

推荐答案
标准C ++非常便携。我开发的主要是针对unix（g ++版本> 3.）
就像系统一样，但我在Windows上编译代码（MS-VC ++ 2003和
以后）从来没有问题。但是，一旦你开始使用系统特定的东西
线程/互斥/微定时器或窗口系统，你可能会遇到小的或大的可移植性问题。如果C ++（和C）会为标准库添加多线程和微定时器，那将是很好的，因为我认为很多现代系统需要或者在某些现实系统中使用它们方式。

Hi,
Standard C++ is very portable. I develop mostly for unix (g++ version > 3.)
like systems but I never have a problem compiling the code (MS-VC++ 2003 and
later) on windows. However as soon as you start to use system specific stuff
threading/mutexes/micro timers or windowing systems than you likely do have
a small or large portability problem. It would be great if C++ (and C) would
add multi threading and micro timers to the standard libraries since I think
a lot of modern systems need or use them in some way.

转换？并不是的。有些编译器会编译为C.
那些通常不会产生任何类型的C代码，可以成功地用于人类。

Convert? Not really. There are some compilers that will compile to C.
Those don''t usually produce any kind of C code that can be used by
humans successfully.
