write a program in C to simulate hotel reservation system.Th

Well actually the program needs to find total number of vacant rooms in a hotel given that hotel has several wings and each wing has 3 floors and each floor has 50 rooms each .Also if any visitor wants to have a room in hotel then the program should search for a vacant room in any wing and allot him the room and program should also calculate the bill of the visitor staying in room .For example if visitor stays for 2 days and the per day price of room in which he stays is 100 the bill is 200.I tried using 2d array of structures in which I created a structure for room which has facilities ,price ,status but I am not getting correct output
