regex

Question

A little tricky, makes me doubt

Answer 1

Looks like I need to look into regex for C++, then...

Answer 2

Oh man, they are terrific! I can't imagine text processing and data extraction/cleansing without them.
Check out my example code on them - so little code, so many possibilities!

Answer 3

C++ STL has <regex>.

Answer 4

Yes, they are. But they are also an EXTREMELY powerful text processing tool.

They can seem unfriendly at first, but trust me - once you manage to tame them, you'll wonder how you managed to live without them until now :)
