# 代码风格

### 标识符

不能以数字开头，可以包含大小写字母，数字，下划线

**易读** . 下划线，如 variable\_name . 驼峰，如 variableName

**语义** . 常量，大写，如 NAME

#### 空隙

常规空隙用ide格式化一下就好。

缩进：四个空格  

一行的最大字符数：79   

大括号： 换行或者不换行都行，但是要统一  

空行分割不同的逻辑代码段

### c

函数的定义中，返回类型单独写一行，函数的名字另起一行。（大概是因为有头文件的原因）

### 参考

有实际参考的比如：  

* \[pointers on c -- chapter2.3 ]\(书籍)
* \[python的官方文档]\(<https://docs.python.org/3/tutorial/controlflow.html#intermezzo-coding-style>) &#x20;
