问题描述
Herb Sutter的 C ++代码标准表示避免过早优化和过早隐藏。但我觉得两者都做同样的事情。所以期待一些帮助澄清这两个概念与他们之间的不同。如果你拿出一些例子，对他人更有好处。
是关于过早优化。但我找不到任何过早的pessimization
Herb Sutter's C++ coding standards says to avoid Premature optimization and Premature pessimization. But I feel both is doing the same thing. So expecting some help to clarify these two concept with the different among them. If you come-up with some examples, It will be more benefit for others.Here is a good explanation about Premature optimization. But I couldn't find any for Premature pessimization
推荐答案
我认为，过早优化的手段是与提前优化相反的：基本上忽略了使用哪种数据结构和算法。
What he means by premature pessimisation, I think, is just the opposite of premature optimisation: a fundamental disregard of which data structures and algorithms to use.
过早优化通常与微分
过早的pessimisation，相比之下，关注高层次的设计的代码架构：一个基本上无效的接口为你的库例如不能通过优化后固定，因为公共接口是在石头上。
Premature pessimisation, by contrast, concerns the high-level design of code architecture: a fundamentally inefficient interface for your library for instance cannot be fixed later by optimising, since the public interface is pretty much cast in stone.
