I'm not sure where one would use it... are there any parser-type functions that take some regex as an argument or something? I just found out that my editor will highlight a line after / as "regex" for C/C++ syntax which I thought was weird...

Answer 1

In the vanilla C++ language there is no support for regular expressions. However there are several libraries available that support Regex's. Boost is a popular one.

Check out Boost's Regex implementation.

PCRE is the de-facto standard regex library for C (and it also works in C++).

(What your editor is doing I don't know. Using a library like PCRE or any of the others suggested doesn't change the syntax of C - your regex definitions will always be held in strings.)
