Great tutorials. I also began to take a course on Udemy. It's called
C++ Tutorial for Complete Beginners. Also on site
http://www.cplusplus.com/doc/tutorial/ and
https://assignment.essayshark.com/co...ence-help.html there are various useful manuals, instructions and you can ask the expert who will help with a specific assignment, which is very convenient. Of course, among other things, many different materials can be found on other resources.
