C++核心准则​NL.10：首选下划线风格名称

NL.10: Prefer underscore_style names

NL.10：首选下划线风格名称

Reason（原因）

The use of underscores to separate parts of a name is the original C and C++ style and used in the C++ Standard Library.

下划线用于分隔名称的各个部分，是C和C ++的原始样式，并在C ++标准库中使用。

Note（注意）

This rule is a default to use only if you have a choice. Often, you don't have a choice and must follow an established style for consistency. The need for consistency beats personal taste.

此规则是默认值，仅在您可以选择时使用。通常，您别无选择，必须遵循既定风格来保持一致性。对一致性的需求高于个人品味。

This is a recommendation for when you have no constraints or better ideas. This rule was added after many requests for guidance.

当您没有约束或更好的想法时，这是一个建议。在许多准则的要求之后添加了此规则。

Example（示例）

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

Stroustrup：ISO标准，但大写字母用于您自己的类型和概念：

• int
• vector
• My_map

Enforcement（实施建议）

Impossible.

不可能。
