I hope this is the right section for my newb question.

I have taken some c++ classes in HS and now in college. The problem is that I am looking over my courses that I have left to take there doesnt seem to be anymore c++ classes... I have learned a great deal in these classes, but I want to learn more. Most of the programing has had all the output on a screen like the comand prompt in windows, so I guess my question is where do I go to learn more? I have looked on google but I dont seem to be finding what I am looking for... I am probably looking in the wrong spots... any advise would be greatly apreciated
