家庭作业？
我不知道这样的冲突。效率的重要性大多数时候都被夸大了。好的设计更重要，而且b $ b提供了更多的优势。一个快速的程序有什么用，如果它有问题，迟到，
并且无法维护？另一方面，精心设计的程序
可以更容易地进行优化（假设有需要 - 精心设计的
软件应该从一开始就非常有效），如果需要，可以移植到
更快的硬件。好的设计（几乎）给出了所有
世界中最好的。 * *应该是你的重点，而不是效率。

Homework?
I''m not aware of such a conflict. And the importance of efficiency is
very overstated most of the time. Good design is much more important and
offers more advantages. What good is a fast program if it''s buggy, late,
and impossible to maintain? On the other hand, a well-designed program
can be optimized more easily (assuming there''s a need - well-designed
software should be very efficient from the start), and can be ported to
faster hardware if needed. Good design gives (nearly) the best of all
worlds. *That* should be your focus, not efficiency.

无论何时你采取不妥协的立场，你都要求发生冲突，
'生活不是吗？
所有语言之间都存在冲突效率和可移植性，因为
程序必须在不同的环境中运行。它们可以在一个特定的环境中高效地使用，但这样做只会降低效率，或者在不同的环境中无法运行。

Whenever you take an uncompromising position you are asking for conflict,
that''s life isn''t it?
All languages have a conflict between efficiency and portablility, because
programs must run in different environments. They can be made efficient for
one particular environment but only at the cost of being less efficient or
unportable on a different environment.

没有。编写既可移植的代码也很容易用C ++编写高效的代码。

There isn''t. It is easy to write code that is both portable and
efficient in C++.
