Let's do something useful! It is a common case when the user's input must be checked using some regular expression. The problem is that there are a lot of regular expression syntaxes, expressions written using one syntax are not treated well by the other syntaxes. Another problem is that long regexes are not so easy to write.
So in this recipe, we are going to write a program that supports different regular expression syntaxes and checks that the input strings match the specified regexes.
This recipe requires basic knowledge of standard library. Knowledge of regular expression syntaxes can be helpful.
Linking examples against the boost_regex
library is required.
