Vending machine - help needed

I've spent a good month trying to teach myself, starting from the beginning, but just don't get it

wvmarle:
You will have to put some effort in it - start by learning C++ basics, and you'll be able to understand the code soon enough. It's not that hard, but it's also not something you can do without learning anything!

I'm not shy for hard work, but I've spent a good month trying to teach myself the very basics, but just don't get it. Not everyone is good at everything - which is my in my original post I asked for help finding someone that does 1:1 lessons / workshops.

Sadly I don't have the time to invest anymore in learning this.

Thanks anyway for your help.
