Question

How can I use this regex in C?

如果我这样做,我就错了:

if (regcomp(&reg, "/[^\]]/", REG_EXTENDED | REG_ICASE) != 0)

error:

warning: unknown escape sequence  ]

提前感谢。

Answer 1

在我从两端逃脱后lash并删除了<条码>/时。

Answer 2

I think you need to escape your backslashes:

from "/[^\]]/" to "/[^\\]\]/"

Answer 3

I like perl , and I also like C/C++. To make the best of both, I wrote a github project to solve this issue.

a short example is here :

P_eval("$a=2;$a=$a**10;"); 
Int("a") ;   // a= 1024  


P_eval("@arr=(0..9);"; 
P_arr_Int_i("arr", 8 );  // => 8
