Is it best through a video or something like brilliant?

Your choice of learning method largely depends on your personal preferences. Some individuals prefer interactive approaches, such as video tutorials, while others favor reading comprehensive materials like books or websites.

learncpp.com is an excellent free resource.
The book C++ Primer by Stanley B. Lippman provides a thorough understanding of the language if you're looking for a more comprehensive study.
If you prefer a  less reading intensive approach, I recommend the Beginning C++ Programming - From Beginner to Beyond course on Udemy by Dr. Frank Mitropoulos.

You could also just watch some free YouTube tutorials but I'd be rather careful as there are a lot of inexperienced people that teach bad or outdated practices.

Definitely check out C++ Weekly by Jason Turner on YouTube once you gained a foothold in the world of C++.
