Hi,
If you wanna learn c++, I do really recommend the video's from TheChernoProject or the thenewboston.
TheChernoProject has good explainations in depth & I find it much easier to understand than "courses" or books.
His playlist for C++: https://www.youtube.com/playlist?list=PLlrATfBNZ98dudnM48yfGUldqGD0S4FFb
thenewboston has great video's too, which cover allot, but his video's about a specific subject aren't aslong as TheChernoProject, which may make it harder to actually understand.

thenewboston has allot of tutorials for allot of languages, so if you wanna learn a specific language, he might have a playlist for it!
Also, I suggest you to try & actually understand it. Not just copy & paste or just listen & watch to the tutorials.
You won't remember things later then, which may annoy you like it did to me
Have fun learning
