Based on Phillip M. Duxbury's C++ Cheatsheet and edited by Morten Nobel-Jørgensen. The cheatsheet focus is both on the language as well as common classes from the standard library. C++11 additions is inspired by ISOCPP.org C++11 Cheatsheet). The goal is to give a concise overview of basic, modern C++ (C++14).
