Description
You are allowed to write everything in one file this time, so long it is organized and the file is not too long. If the file gets too long, please split it into multiple .h and .cpp files, and have a main.cpp that #includes the .h files, and can be used to call the functions prototyped in them.
All the files you produce must be able to exist within a single project. You will submit these files via github as normal.
Setup
Write a function named print_vector that takes a const std::vector
