The Practice of Programming Notes

至少，每个名字应该被能显示这个特殊值的作用的所替代。

• 全局用描述性的名字，本地用短名。

  i和j用于循环指数，p和q作指针，s和t作字符串

  clarity is often achieved through brevity.

  pch 字符指针

• 一致性
• 为函数用主动名字

  if （isoctal（c））。。。 使得是或否清晰

• 正确性 ： 内容和名字一致性

• 缩进来显示结构
• 表达式用自然形式
• 用括号解决含糊
• 分解复杂的表达式
• 清晰 the goal is is write clear code, not clever code.
• 小心副作用

i++ 有副作用

• 使用一致的缩进和括号风格 By the way, if you work on a program you didn't write, preserve the style you find there. When you make a change, don't use your own style even though you prefer it. The program's consistency is more important than your own, because it makes life easier for those who follow.
• 用术语来保持一致性 For an infinite loop, we prefer

 for (;;)
 ...
 but
while (1)
 ...

is also popular. Don't use anything other than these forms.
