.cc和.cpp文件后缀有什么区别? [英] What is the difference between .cc and .cpp file suffix?
问题描述
.cc 和 .cpp 文件扩展名有什么区别?
What is the difference between .cc and .cpp file extensions?
我从Google得知它们都是C ++语言，但是我不确定它们之间的区别.
From Google, I learned that they are both from the C++ language, but I am unsure of differences between them.

公约.
从历史上看，C ++源文件的后缀是 .C .第一次移植C ++时，这引起了一些问题到文件名中大小写无关紧要的系统.
Historically, the suffix for a C++ source file was .C.
This caused a few problems the first time C++ was ported
to a system where case wasn't significant in the filename.
不同的用户采用了不同的解决方案: .cc ， .cpp ， .cxx 以及其他.今天，在Unix之外世界上主要是 .cpp .Unix似乎更经常使用 .cc .
Different users adopted different solutions: .cc,
.cpp, .cxx and possibly others. Today, outside of the Unix
world, it's mostly .cpp. Unix seems to use .cc more often.
对于标头，情况更加令人困惑:无论是什么原因，最早的C ++作者决定不区分在C和C ++的标头之间，并使用 .h .
For headers, the situation is even more confusing: for whatever
reasons, the earliest C++ authors decided not to distinguish
between headers for C and for C++, and used .h.
如果项目中没有C，这不会引起任何问题，但是当您开始必须同时处理这两个问题，通常这是一个好主意区分可以在C( .h )中使用的标头以及那些不能( .hh 或 .hpp )的文件.
This doesn't cause any problems if there is no C in the project, but when you
start having to deal with both, it's usually a good idea to
distinguish between the headers which can be used in C (.h)
and those which cannot (.hh or .hpp).
此外，在C ++中，许多用户(包括我自己)都喜欢保留模板源代码和内联函数在单独的文件中.哪一个，虽然严格来说是头文件，但往往会得到另一个一组约定( .inl ， .tcc ，可能还有很多其他).
In addition, in C++, a lot of users (including myself) prefer keeping the template
sources and the inline functions in a separate file. Which,
while strictly speaking a header file, tends to get yet another
set of conventions (.inl, .tcc and probably a lot of
others).
对于标头，它对编译器绝对没有影响.
In the case of headers it makes absolutely no difference to the compiler.
对于源文件，不同的结尾将导致编译器采用不同的名称语.但这通常可以被覆盖，我使用了 .cc 早在VC ++将其识别为C ++之前就已经使用VC ++.
In the case of source files different endings will cause the compiler to assume a different
language. But this can normally be overridden, and I used .cc
with VC++ long before VC++ recognized it as C++.
