Have you done any research into regex with C, do you have some code to show us? – kevlar1818 May 24 '12 at 16:52

You might like to look for a library with it already coded. C uses librarys to allow you to include other peoples code into your work. I assume there are many regular expression librarys for you to use already to go!

No prob! Happy coding! If you have a lot of stuff to code in C you may like to check out K&R or some other nice references, then just skim them over so you learn the rough idea of how the language works :). – user1399238 May 24 '12 at 17:05
