设计原则，最佳实践和设计模式为C（或一般程序编程）？ [英] Design Principles, Best Practices and Design Patterns for C (or Procedural Programming in general)?

问题描述

存在任何已知的设计原则，最佳实践和设计模式，同时设计一个C项目，一个可以遵循？或有用的设计原则，在一般程序​​（必要）编程？

Are there any known design principles, best-practices and design patterns that one can follow while designing a C project? Or useful design principles for procedural (imperative) programming in general?

推荐答案

信息隐藏 - 由尔格的信奉（软件基础）。

Information hiding - as espoused by Parnas (Software Fundamentals).

报头和知名度的精细化管理：

Careful management of headers and visibility:

• 中，可以从外界被隐藏应是源文件的一切;只有记录的外部接口予以曝光。


• 被暴露在头声明的一切。


• 这头被用来在需要的功能（并在它被定义）。


• 标题是自包含的 - 当你需要它，你使用它，你不用发愁什么其他的头我也有包括因为头保证了它的工作方式，包括任何需要使它工作。



• 标题是自保护 - 。因此，如果它被包含多次不要紧

• Everything in a source file that can be hidden from the outside world should be; only the documented external interface should be exposed.
• Everything that is exposed is declared in a header.
• That header is used where the functionality is needed (and where it is defined).
• The header is self-contained - when you need it, you use it, and you don't have to fret about 'what other headers do I also have to include' because the header ensures it works by including anything it needs to make it work.

• The header is self-protected - so it does not matter if it is included multiple times.

#ifndef HEADER_H_INCLUDED
#define HEADER_H_INCLUDED
...rest of header contents, including other #include lines if necessary
#endif /* HEADER_H_INCLUDED */

设计的函数集在对象（一般结构）的工作 - 并使用这些功能，而不是周围的结构在code，它在使用它的内脏戳。把它看成是自我强加的封装。

Design sets of functions to work on 'objects' (usually structures) - and use those functions rather than poking around the innards of the structure in the code that is using it. Think of it as self-imposed encapsulation.
