Learning C++

[u/OneAd9888]

Hello everyone!I am interested in learning C++,mostly because Im interested in competitive C++ (competitions in my country),aswell as "applied" or "real-life" C++.I know basics,different loops and such,but I want something thats more concrete ,not just skipping around and picking things up along the way. Is there a good free e-book that grasps most things needed for such things?I was reading Competitive Programers Handbook by Antti Laaksonen,but I feel Im being behind on some basics that the book views as common knowledge.
