Hostel Management System (C++ code)

/*Please kindly note that there are many mistakes in this project, as no proper reservation is done into the library files, and the updates are not done on the reservation of rooms. Similar other faults are present. However if you want to look at the basic structure and basic features of the Hostel Management System (HMS), then this is a good source for you, it also uses very basic C++ and OOP concepts in it so it is easy to understand and update.*/
