问题描述
在Stroustroup正在设计C ++，他的目标之一是，C ++是一样多的C的超集越好。我明白，这是不是100％的情况下，但多数有良好的C code也C ++ code。
When Stroustroup was designing C++, one of his goals was that C++ were as much a superset of C as possible. I understand that this is not 100% the case, but most of good code in C is also C++ code.
但我听到C99支持很多事情，C ++不（像VLA），并有甚至将是C1X或C0X不管它被称为。因此，C ++是一个超集仅 老的 C89，从那时起C和C ++是很多独立开发pretty？
But I am hearing that C99 supports many things that C++ doesn't (like VLA) and that there is even going to be C1x or C0x whatever it's called. So, C++ is a superset of only old C89 and from then on C and C++ are developing pretty much independently?
推荐答案
C ++是C89 / C90的近超集。 （我不建议写code具有能够编译为C或C ++的目的，虽然。）此后，C99分歧。新的C ++标准（通常称为的C ++ 0x）将有一些尝试更加兼容，但不会有这样的事情作为C99变长数组。斯特劳斯已经EX pressed失望与一些Ç委员会的行动，显然是有期望他们尽量保持接近C ++的兼容性。
C++ is a near superset of C89/C90. (I don't recommend writing the code with the purpose of being able to compile it as either C or C++, though.) Since then, C99 diverged. The new C++ standard (often called C++0x) will have some attempt to be more compatible, but isn't going to have such things as the C99 variable-length arrays. Stroustrup has expressed disappointment with some of the C committee's actions, apparently having expected them to try to keep closer to C++ compatibility.
所以，是的，语言是发散。
So, yes, the languages are diverging.
