The other link posted here is great info but might be a bit overwhelming. Some of the highlights of modern C++ to look into: Lambda functions Smart pointers = less need for * Move semantics = less need for pointers, efficient pass/return-by-value Type inference with `auto` `nullptr` = strongly-typed null pointer type sans macros `constexpr` = compile-time programming sans macros Deleted functions = can prevent things like accidental copies Range-based `for` = very similar to Java's for-each That should mostly catch you up from C++03 to C++11-ish (language features only; there's plenty more to explore with library changes). C++14 and 17 had some refinements to those items so review the above in a current context for additional enhancements to them. C++20 adds some major things like concepts and modules, but starting there might not be the best idea to get up to speed. (I'm a C++ amateur and hobbyist, so I might not be using 100% correct terms above! I'm also a very, very minor SerenityOS contributor.)
