C问题......小OT [英] C question...little OT

问题描述

我可以问一些经常困扰我的事情。

在K& R中，例如（p106），在解释他们的strcmp版本时，

指针两个字符串给出为* s和* t。

有谁知道这个约定是如何开始的。是s吗？代表

" source"例如，字符串。或者它就像s =" string"一样简单，

i =" integer"下一个字符串将是t，u，v等。

谢谢

May I ask something that has often puzzled me in C.
In K&R, for example (p106), in explaining their version of strcmp,
pointers to the two strings are given as *s and *t.
Does anyone know how this convention started. Does the "s" stand for
"source" string, for example. Or is it as simple as s="string",
i="integer" and the next string would be t, u, v, etc.
Thanks

我希望不是，因为那不是来源 - 它是目标！

I hope not, because that''s not the source - it''s the target!

或者它就像s =" string"，

i =" integer"

Or is it as simple as s="string",
i="integer" and the next string would be t, u, v, etc.

是的，我认为这是最可能的解释。当然，当我

演示strcpy时，我使用char * u = s来保存返回值。

Yeah, I think that''s the most likely explanation. Certainly, when I
demonstrate strcpy, I use char *u = s to hold the return value.

也就是说，真正的大师使用一个字母的名字。
