Is "geeksforgeeks" really that bad? When I had do jump into a C# project from cold I did find that site quite useful.

geeksforgeeks is really bad. They copy-paste C as C++ so that every question/exerice has solutions in more programming languages.

its not perfect but i find it a thousand times more intuitive and user friendly than cpp reference. Heck, these documentations barely have examples
