Class

Question

I have some problems in understanding class in c++ did anyone have best source to read?

Answer 1

I also had trouble initially to understand all the OOP stuff. And that's no surprise - it's the next layer of complexity after functions.
I see you haven't posted any code here. I don't know how much code you have secretly written, but this is really important: Get actual coding experience!
Choose a specific task (no problem if it's easy) and solve it. Then more and more. You need to learn to think in code.
After a while, due to experience and training, suddenly OOP (other stuff as well) will start to make more sense to you.
