正则表达式在C ++ visual studio 2010中 [英] Regex in C++ visual studio 2010

问题描述

我想了解如何使用visual studio 2010在C ++中使用regEx.



我有以下要求。

Hi,

I wanted to understand how can I use regEx in C++ using visual studio 2010.

I have below requirements.

RegEx :   [0−9]{3}[0−9a−zA−Z]{3} [0−9a−zA−Z]{2} [0−9]  //Regular expression, 

Here there is range of valid chars in [] and value inside {} denotes the number of charactes that should comply with rule.


[0-9]{3} means that first three charcters of string should be a number in range 0 to 9.

[0−9a−zA−Z]{3} means that next 3 chars of string can be anything in range 0-9 or a-z ot A-Z.

以下是考虑上述规则的有效和无效字符串。

Below are valid and invalid strings considering above rule.

120 aBZ K8 7 - Valid


AX0 aBZ K8 7 - Not Valid


120 @1k0 _1 _  - Not valid


120 1BZ 18 7 - Valid

任何帮助表示赞赏。
