NL.8: Use a consistent naming style

NL.8:使用一致的命名方式

Rationale: Consistence in naming and naming style increases readability.

基本原理:命名和命名样式的一致性可以提高可读性。

Note(注意)

There are many styles and when you use multiple libraries, you can't follow all their different conventions. Choose a "house style", but leave "imported" libraries with their original style.

存在很多样式,当您使用多个库时,不可能遵循所有不同的约定。选择一种风格作为“家庭风格”,但保留“导入”库的原始风格。

Example(示例)

ISO Standard, use lower case only and digits, separate words with underscores:

ISO标准仅使用小写字母和数字,并使用下划线分隔单词:

  • int
  • vector
  • my_map

Avoid double underscores __.

避免双重下划线。

Example(示例)

Stroustrup: ISO Standard, but with upper case used for your own types and concepts:

Stroustrup:使用ISO标准,但大写字母用于您自己的类型和概念:

  • int
  • vector
  • My_map
Example(示例)

CamelCase: capitalize each word in a multi-word identifier:

CamelCase:将多单词标识符中的每个字大写:

  • int
  • vector
  • MyMap
  • myMap

Some conventions capitalize the first letter, some don't.

有些约定将首字母大写,有些则没有。

Note(注意)

Try to be consistent in your use of acronyms and lengths of identifiers:

尽量使首字母缩写词和标识符的长度保持一致:

代码语言:javascript复制
int mtbf {12};
int mean_time_between_failures {12}; // make up your mind
Enforcement(实施建议)

Would be possible except for the use of libraries with varying conventions.

除了使用具有不同约定的库以外,都是可能的。
