I also had some problems when following the video. but after spending time and even asking chat gpt, I was either missing a minus (-) , a semicolon, or a letter like player_1_p and player_1_dp. So you have to look back at the code carefully and see what is wrong.

somethings my professor though me is writing the code out on paper and finding out what each piece of code does aka taking notes on the code. you'll also need to be able to recognize classes and pointers to understand the parts in this video. you can also use an AI to break down pieces of the code. some of the stuff such as the windows you dont "really" need to know how it works just that it's windows class for windows development. but microsoft does have a documentation you can read through on what each part does.

Hey, can you explain how did he use printf?

@@Priyanand-kj5ch what do you mean?

You probably did not define it. That means i think you haven't included that file yet. Do it and probably it will be gone.

@@hadiaabq7981 what file too include? Thank you

@@LostSol25 he basically decalared the variable vk_code. He DECLARED it. Check your declaration. Don't need to include anything.

@@hadiaabq7981 I dont understand because he declared b, vk in the define attribute but it says vk is undefined. It doesn't recognise the paramaters

Solved

Just finished this video didn't understand a lot but felt good after seeing the box. Learned a lot
