Answer 2

Learn about range based for loops and the auto keyword. They make you far more productive and your code more readable.

Answer 3

Everything 「ＨＡＰＰＹ ＴＯ ＨＥＬＰ」 and Kaynn Cahya mentioned + I'd suggest learning new things from C++11 to C++17. Things like smart pointers, variadic templates (generally metaprogramming) and multithreading. And of course Unit tests are nice-to-have.
