Wiki上的C++哲学

Philosophy[edit]

Throughout C++'s life, its development and evolution has been informally governed by a set of rules that its evolution should follow:^[9]

• It must be driven by actual problems and its features should be useful immediately in real world programs. 由现实问题驱动而产生的语言
• Every feature should be implementable (with a reasonably obvious way to do so). 每种特性都是可以实现的
• Programmers should be free to pick their own programming style, and that style should be fully supported by C++. 程序员应该自由的使用自己的方式来编程
• Allowing a useful feature is more important than preventing every possible misuse of C++. 允许使用一个特性比滥用特性更重要
• It should provide facilities for organising programs into well-defined separate parts, and provide facilities for combining separately developed parts. 可以很好的组织和分发任务进行团队编程
• No implicit violations of the type system (but allow explicit violations; that is, those explicitly requested by the programmer). 没有隐含的违反系统的类型
• User-created types need to have the same support and performance as built-in types. 用户创建的类型可以与内建类型有同样等级的支持和性能
• Unused features should not negatively impact created executables (e.g. in lower performance). 未使用的功能不应对创建的可执行文件产生负面影响
• There should be no language beneath C++ (except assembly language). There should be no language beneath C++已经是终极语言了，而不是还有语言去扩展它
• C++ should work alongside other existing programming languages, rather than fostering its own separate and incompatible programming environment. C++应该与其他现有的编程语言一起工作，而不是建立自己独立且不兼容的编程环境
• If the programmer's intent is unknown, allow the programmer to specify it by providing manual control. 如果程序员的意图未知，则允许程序员通过提供手动控制来指定程序员的意图。

我认为总结为两句话：1. C++来自于现实世界的实际需求，是实践派而不是理论派 2. 允许程序员自由的使用自己的方式编程，而且允许内建各种类型，总之就是很自由、很强大。
