这不是更快。

我将不胜感激任何建议。

It isn''t faster.
I''ll appreciate any suggestion on this.

去接受不同的采访。

Go to different interviews.

可能他们想检查你是否理解C

和C ++之间的区别。如果你这样做了，你会回答说每个C程序都可以用C ++表示，只需要很少的语法清理和

声明，而且通常是相同的编译器用于C和C ++。所以给了一个快速的C程序，你也有一个同样快的C ++程序。


然后你可能会继续谈论一些这个表现

可以用更短的开发时间和一般可维护性进行交易，而不是C ++，而不是C.


并得出结论，这两种语言本身都不比其他语言更快，但是C ++为您提供了更广泛的实用开发技术：所有

的C，加上加号（啊，_那是什么，++代表什么！）。

A：热门帖子。

问：什么是usenet和电子邮件中最烦人的东西？

Probably they wanted to check whether you understood the difference between C
and C++. And if you did, you would have answered that every C program can
also be expressed in C++ with just minor cleaning up of syntax and
declarations, and that very often the same compiler is used for C and C++. So
that given a fast C program, you also have a just as fast C++ program.

And then you might have gone on to talk about how some of that performance
could be traded for shorter development time and general maintainability, in
C++, but not in C.

And concluded that neither language is inherently faster than the other, but
that C++ gives you a much wider range of practical development techniques: all
of C, plus plus (ah, _that_''s what the "++" stands for!).

问题就是问哪个更快，兰博基尼或者法拉利的b
。答案应该是，它们的速度和它的驱动器一样快。

技能可以让它们去。

The question is like asking "which is faster, a Lamborghini or a
Ferrari". The answer should be, they''re only as fast as it''s driver
skill can make them go.
