I Suck

I'm taking an intro C++ class, the only thing I have experience with is Java (only thing offered and my self-teaching has been with irrelevant things such as lisp) and have a quick question.

I'm trying to break the lines of a text file into separate strings to be input into a struct, using a colon as the token. I have no idea how to go about this in C++ though, can someone shed some light here?

I don't need nor want for someone to write my program for me, I'm just not sure how to segregate the lines into distinct strings.

Which scenario do you expect you would have to use strtok from multiple threads yet not needing performance? If you look out every other thread for the duration of tokenization then you basically have a single threaded program.
