Can i have more hints please?

Question

I have no more hints

Answer 1

I guess you mean hints for the C++ course. You need XP to use them, and XP is earned when you answer questions correctly.
Perhaps, it would be better to read lessons carefully (and comments to the lessons too, there is a lot of useful information), then try to answer to get knowledge and XP😊
