Re: [Dev-C++] Choose a word from a .txt file

I think what Per refers to is the overhead of initializing and regex
library and calling upon it. What appears as a single function call is
probably several 100 lines of code underneath.

And for small programs it's often better to leave out library dependencies
and reduce compilation times.

Just my 2 cents.
