Dear Mr Flips,
Here, we have a lot of good friends to learn from. So, go to the course section and do your best to learn and practice every single lesson. A lot of basic questions have been answering there. If you came up with something that you couldn't find your answer, send a question to QA and don't forget to use the search bar first.
Good luck my friend.
Well, there are a tremendous number of projects you can do using c++. But I encourage you to learn the basics of the C++. Then smooth your way towards advanced and real world problems. BTW, Try to buy a GOOD book on C++ as your reference. Search through the QA section and you'll find a lot of resources.
for game development in c++ check this resource it will help.
