C++17/20 solutions to Advent of Code 2018

This repository contains my solutions to Advent of Code 2018. The code is written in C++17, making use of some libraries implementing C++20 features.

The source file(s) for each day are in their own directories. There is no build system or anything like that: just cd to a directory and compile using the command line. The solutions have been tested with GCC 8 and Clang 7. They may or may not work with MSVC.

To save typing, the file common.hpp in this directory #includes many headers which are re-used in most of the solutions. You may wish to precompile this file to improve your build times.
