tour-of-cpp

This repo is inspired by many of the concise examples of idiomatic modern C++ that appear in the book A Tour of C++ by Bjarne Stroustrup. I initially started the repo to expand and experiment with the specific examples from the book, but I have since added a lot of new examples of modern C++ features that are not from the book.
