Tutorial c++

This is my first time posting something on Unreall Forum, I don’t know if this section is a right place for my question. I am not a native so probably I will have some grammar mistakes sorry for that.
I have took part in some online course after some videos I felt I can’t keep up with them, basically I don’t understand what I am coding ;(. I wonder if there are a good tutorial for beginners like me. Thank You.

this is what I and most other people used, he goes through everything and it is slow with a set task every video so its very good for beginners.
