/*
create a program that will allow you to enter events organizable by hour.
There must be menu options of some form, and you must be able to easily edit, add, and delete events
without directly changing the source code.

(note that by menu i dont necessarily mean gui. as long as you can easily access the different 
options and receive prompts and instructions telling you how to use the program, it will probably be fine)

well it meets the requitements. i dont know what they mean "organisable by hour". Sorted maybe ?

theres no input validation, or buffer overflow checking.
it would also benefit from a more dynamic array.
limited to 5 events.
