一般认为C++ 是 C 的 superset. C 有的功能 C++ 都有，而 C++ 多了Object-
oriented programming 和很多 library functions. 据说C 和 C++ 的速度也差不多。
那么C 还有什么优势吗？ | s**i

发帖数: 25 | 4 For same quality C++ and C codes, I would say C is faster. Just like
Assembly will be faster than C. The features that are unique to C++ I can
think of are:
object oriented, Encapsulation, inheritance, polymorphism, exception
handling, class, templates, Function overloading, virtual func, new/delete
instead of malloc/free, namespace, type casting, overloading of operators,
inline func, pure virtual func, scope rule
In short, more powerful. | h***z

faster.
But for the current hardware, the difference is not too big.
