# C++ Solutions to Advent of Code
This repository contains solutions to various years of the [Advent of Code](https://adventofcode.com)
puzzles. All solutions are written in C++. The solutions aren't designed to be nice or
pretty. Instead, I am using it as an experiment in understanding how I approach solving
problems.

## Running the Puzzles
There is a driver script (`./driver.sh`) in the root of the checkout. It will build and run specific tests. Example
use is as follows:

Note that some of the puzzles require OpenSSL for the MD5 implementation. On macOS this also requires you to pass an appropariate value for `OPENSSL_ROOT_DIR` to cmake. On x86 this is `-DOPENSSL_ROOT_DIR=/usr/local/opt/openssl` and on AArch64 this is `-DOPENSSL_ROOT_DIR=/opt/homebrew/opt/openssl`.

## Sources

Within the directory there are the following files:
* `puzzle-DAY-NUMBER.cc`. The source for puzzle NUMBER on day DAY in the year.
* `driver-DAY-NUMBER.sh`. If present this is used as the driver to run that puzzle.
* `puzzle-DAY-NUMBER.CMakeLists.txt`. If present this is included by `CMakeLists.txt`. The variable `${puzzle_name}`
contains the name of the puzzle target. Some puzzles use this to depend on OpenSSL.

### Command Line Interface
The executable command line interface should just take the input in on standard-input and print its
result on standard-output.
If this is not possible the script `driver-DAY-NUMBER.sh` within the year directory should be provided. It should take
two arguments - the executable to run and the input file to use.
