I don't really get using functions with parameters, I get basic function work but not with parameters. I've tried creating a programming, but I'm not sure what to do and I end up making a copy of someone else's problem. I've tried re-reading what I learn from but that didn't help.
So what did you guys do when you weren't 100% on something?
If that doesn't help, then get a good book on C++ and work through that too. I'd say the important thing is not to rush things. Stay with each topic until you understand it as best you can.
Make sure to write your own code and try any questions which are set at the end of each topic.
