好的变量缩写

[DjvuLee]

自己觉得 3~4 个字符表示的缩写给程序变量命名比较好，即避免了单个字符的完全没有意义，也避免了冗余，我自己个人编程中觉得下面这些是不错的，不知道大家通常有哪些不错的缩写？

idx: index
cnt: count
src: srouce
dst: destination
usr: user
ptr: pointer
msg: message
buf: buffer
len: length
dat: data
lib: library
inc: increase
dec: decrement
rsp: response
req: request

addr: address
conn: connection

@NearTan In the original Unix implementations, /usr was where the home directories of the users were placed (that is to say, /usr/someone was then the directory now known as /home/someone ). In current Unices, /usr is where user-land programs and data (as opposed to 'system land' programs and data ) are. The name hasn't changed, but it's meaning has narrowed and lengthened from "everything user related" to "user usable programs and data". As such, some people may now refer to this directory as meaning 'User System Resources' and not 'user' as was originally intended.

个人习惯没有超过 5 个就不用缩写

[tabris17]

src: srouce
dst: destination
ptr: pointer
msg: message
buf: buffer
len: length
lib: library
addr: address
conn: connection

这几个长的可以有，而且很常用，一目了然，其他几个本来就很短，没必要再缩写了

When Ken Thompson was asked if he redid UNIX, what would he do differently, he said that he'd spell creat with an e.

user 竟然用 usr 。。。 data 缩写为 dat 也没有意义， response 缩写为 resp 的比较多

[Raito]

srouce? 打错了吧

[kappa]

inc: increase
dec: decrement

这。。。

[lxrmido]

pwd/passwd/password
desc/description
fs/filesystem
res/resource
db/database

最令人发指的是把变量名缩的只剩一个字符
把 request 缩成 r
把 header 缩成 h
把 packet 缩成 p

[pangtianyu]

我认为最好的变量就是 a 到 z 一共 26 个字母 不够就 aa ab 一直下去

尽量不缩写，靠 IDE/编辑器的自动提示来提高效率
