什么是C和C之间的主要区别++时，你会选择一个比其他？ [英] What are the major differences between C and C++ and when would you choose one over the other?

问题描述

对于那些与既有经验，有什么主要区别？对于一个初来乍到要么，这将是更好地学习？在那里，你会选择C ++情况下，您可以选择C，但随后其他情况？它是使用的情况下作业的最佳工具或者一个比另一个更显著。我知道C ++是一个的C强化，但它是在'83创建并没有完全取代Ç所以必须有它更多的东西。

For those of you with experience with both, what are the major differences? For a newcomer to either, which would be better to learn? Are there situations where you might choose C but then other situations where you would choose C++? Is it a case of use the best tool for the job or one is significantly better than the other. I know C++ is an "enhancement" of C, but it was created in '83 and hasn't completely replaced C so there must be something more to it.

我知道这个问题是主观的，我不是要启动任何宗教战争，所以请尽量尽可能客观。清除的长处和短处和比较。

I know this question is subjective and I am not trying to start any religious war, so please try to be as objective as possible. Clear strengths and weaknesses and comparisons.

推荐答案

虽然C是一种纯粹的过程语言，C ++是一个的多范式的语言。它支持

While C is a pure procedural language, C++ is a multi-paradigm language. It supports

• 泛型编程：允许写code一次，并用不同的数据结构使用它
。

• 元编程：允许利用模板在编译时生成高效code


• 检查：允许检查在编译时某些属性：没有一个前pression有哪些类型？多少个参数做了功能有哪些？每个特性有哪些类型？


• 面向对象程序设计：允许程序员在程序面向对象的，具有先进的功能，如多重继承和私有继承。


• 程序编程：允许程序员将没有任何类别的功能。具有先进的功能，如ADL允许写入干净code从某些类别的具体解耦相结合。

除了这些，C ++在很大程度上保持着C code兼容性，但也有一些差异。这些可以在C ++标准的附录D与原因和可能的固定，使C code时有效C ++ code来了解，共同提高。

Apart from those, C++ has largely kept compatibility with C code, but there are some differences. Those can be read about in Annex D of the C++ Standard, together with reasons and possible fixed to make C code valid C++ code.
