Difference between-regex and-name of find 1. the biggest difference with-name and-iname is that-regex uses the entire result output by find (different from the absolute path name) as the object to be matched, not just the last part of the result www.2cto.com example/The tmp directory contains only aaa, aa, 1, 2. The find-name "a *" files can be found in aaa and aa, while the find/tmp-

C # provides a very powerful function for the use of regular expressions, which is the Regex class. This package is included under the System.Text.RegularExpressions namespace, and the DLL where the namespace is located basically does not need to be added separately in all project templates and can be used directly.1.

Generally, we can determine whether a value exists in a string. contains, in fact, there are many methods to determine the existence of a value in a string, the most common is the aforementioned string. contains, which are commonly used, are also string. indexof and RegEx. match. Let's talk about Code directly. In general, the implementation of functions is the most important. The author's words are only effective for those who are interested.

call the rpattern function, for example, match () or substitute () can get the matching result. If the match ()/substitute () call fails, the function returns false. If the call is successful, the function returns true. In this case, the match_results object stores the matching results. See the sample code:
#include
Program output will be:
match success!price: $12.34
You can read the Greta document to learn details about the rpattern object and learn how to customize search policies to improve

RegEx library Installation Summary
After learning regular expressions, I am eager to implement some functions through programming. I learned from the Internet that the boost. RegEx Library provides what I want. It is no exaggeration to say that I have been happy for several days because I know the boost library...
So, to get started, you have to do some trouble to use the boost library instead of an include
[C/C ++ 11] _ [primary] _ [use regular expression library regex]The scenario regular expression is easy to replace when dealing with a very large number of string searches. If the string matches a little complex, it cannot be done without a regular expression. C ++ 11 provides us with a regular expression library. it is easier to use than boost's regular expression library. it must be funny to engage in Java. This is a standard feature of Java. How ca
