（编程）各种语法样式 [英] (Programming) Various Syntax styles

问题描述

大多数（如果不是全部）

编程语言都有大量的语法风格。


例如，一种语法风格（我当前一）：


....

int main（）

{

for（ int i = 0; i <50; i ++）

{

cout<< Hello World！\ n;

j = 2 * i + 1; //一些奇怪的计算

}


返回0;

}


但我正在考虑改变，改变一种在

编程语言中使用得更广泛的风格。如果我似乎不喜欢它，我将返回我的

当前的一个...新的风格是：


int main（）{

for（int i = 0; i< 50; i ++）{

cout<< Hello World！\ n;;

j：= 2 * i + 1;

}


返回0;

}


我现在似乎没有真正习惯它（因为它只是开始）。

我想要改变，因为在很多地方我看到了第二个

风格，所以我认为它更好（看起来）。

我想改变因为在很多地方我看到了第二种风格，所以我想它（看起来更好）。

你最喜欢的是什么？?????????????????????????????????????????????????????????举例说明是否需要

没有最好的编码风格。你选择哪种编码风格并不重要，只要它是一致的。如果您使用与周围其他人相同的

编码样式，它也会有所帮助。在我工作过的所有地方中，首先是首选的编码风格。因为我已经习惯了这种风格，所以格式化的代码格式比第二种风格更容易为我阅读。我希望

对于习惯于第二种风格的人来说是另一种方式。


如果你独自工作，选择你最喜欢的东西。如果你在一个小组中工作，那么使用其他人使用的编码风格

。除此之外，我认为没有理由支持
开关样式。

单独工作时使用你喜欢的风格。当你在一个小组中工作时使用共同的风格。


至少在一个源文件中保持一致。


缩进的标签是邪恶的，但不像混合标签和空格那样邪恶。

用你的例子我有趣的编码风格是：


int main（）{for（int i = 0; i< 50; i ++）{cout<<"" Hello World！\ n" ;; j = 2 * i + 1;

//一些奇怪的计算

}返回0;}


它是通过以下方式获得的C程序：


/ ************************文件：cz.c ***** *****************

已经证明C或C ++程序中的错误数量

是成比例的到源文件的行数。

这个程序戏剧性地减少了错误的数量，减少（最多99％）源中的行数。

显然是由这个程序运行的源代码：

语义等同于原始的

但它的可读性较差！

尝试所有表格：

cz cz.c cz_short.c

cz -256 cz.c cz_small.c

cz -30000 -X cz.c cz_atom.c

cz -0 cz.c cz_long.c

获得：

cz_short.c（200行长）

cz_small.c（118行长）

cz_atom.c（27行长）

cz_long。 c（2746行）

来自：
cz.c（639行）

There is a LARGE number of syntax styles in most (if not all)
programming languages.

For example, one syntax style (my current one):

....
int main()
{
for (int i = 0; i < 50; i++)
{
cout << "Hello World!\n";
j = 2*i+1; //some weird calculation
}

return 0;
}

But I am thinking of a change, a change to a style more widely used in
programming languages. If I seem not to like it, I will return to my
current one... The new style is:

int main() {
for (int i = 0; i < 50; i++) {
cout << "Hello World!\n";
j := 2*i+1;
}

return 0;
}

I seem not to be really used to it now (cuz it''s just the beginning).
I was thinking to change because in many places I saw the second
style, so I suppose it''s better (looking).

WHAT IS YOUR FAVORABLE SYTLE???????????????? give an example if
necessary

There is no "best" coding style. Which coding style you choose is not
important, as long as it is consistent. It also helps if you use the same
coding style as everyone else around you. Of all the places I have worked
the first coding style prefered. Since I''m used to that style, code
formatted that way is easier to read for me than the second style. I expect
it to be the other way around for people used to the second style.

If you work alone choose whatever you like best. If you work in a group use
the coding style everyone else uses. Other than that I see no reason to
switch styles.

Use the style you prefer when you work alone. Use the common style when
you work in a group.

At a minimum be consistent within one source file.

Tabs for indentation is evil, but not as evil as mixing tabs and spaces.

with your example my funny coding style is:

int main(){for(int i=0;i<50;i++){cout<<"Hello World!\n";j=2*i+1;
//some weird calculation
}return 0;}

It''s obtained by the following C program:

/************************ File: cz.c **********************
It has been proved that the number of errors in a C or C++ program
is proportional to the number of lines into the source files.
This program dramaticaly reduce the number of errors,
reducing (up to 99%) the number of lines in your sources.
OBVIOUSLY a source code that is run by this program:
is semantic equivalent to the original
but it is less readable !
Try all forms:
cz cz.c cz_short.c
cz -256 cz.c cz_small.c
cz -30000 -X cz.c cz_atom.c
cz -0 cz.c cz_long.c
to obtain:
cz_short.c ( 200 lines long)
cz_small.c ( 118 lines long)
cz_atom.c ( 27 lines long)
cz_long.c (2746 lines long)
from:
cz.c ( 639 lines long)

1. Correct from:
sscanf(argv[i]+1, "%ld", &maxOutLen)
to:
sscanf(argv[i]+1, "%d", &maxOutLen)
2. Correct from:
static char * operator[] = {...
to:
static char * operatorString[] = {...
3. Operators added to operatorString:
%%%% ... <> <% %> <: :> %%
4. Introduced the function isIdientifierLetter
5. Changed from:
*n = *n+1;
to:
(*n)++;
6. Correct from
#if defined(__STDC__) || defined(__cpluscplus)
to:
#if defined(__STDC__) || defined(__cplusplus)
7. Many casts added to the result of memory allocators
8. Correct from:
static forceNewLine(void)
to:
static void forceNewLine(void)
1.2 Dec 12 1994
1. Recognize as preprocessor line a line starting with %%
2. Now may be also compiled by pre-ANSI-C compiler
1.3 Aug 04 1997
1. Third paramter of strncmp is a size_t
2. Many int casted to char
3. Changed the default for maxOutLen from 80 to 70
