## Input Files
Companies like Uber and Lyft maintains all drivers and uers information in their database, but database is way beyond the scope of this course, and therefore we will just store drivers information and riders information in two simple text files, [drivers.txt](drivers.txt) and [riders.txt](riders.txt). Like previous assignments, in this assignment you will once again read these files as the input of your program, parse them so as to retrieve drivers and/or riders information, and store them in your own data structures. In this assignment, you are not allowed to use *std::vector*, or any data structures we have not discussed in this class. Instead, you must use *std::list* to store drivers and riders. You are recommended to use one *std::list* instance to store all drivers, use another *std::list* instance to store all riders.
