COP $2220$: Programming in CExam $2-$ Hotel Reservations: $(21$ points$)$This exam covers all material up to$,$ and including, two$-$d arrays.Read ALL the following instructions CAREFULLY BEFORE writing any code. If you do not understand something, email me ASAP for clarification.Create a C program and save it as cop$2220$Exam$2$YourInitials.c in your cop$2220$ folder. Example: Fred Flintstone would save the file as cop$2220$Exam$2$FF$.$c$($I will take off points if the file is not named exactly as required.$)$The program is designed to help the manager of a hotel keep track of room occupancy. The hotel will be represented by a two$-$d array $(3$ rows, $5$ columns$)$ of integer values. The rows represent the floors of the hotel with row $0$ being the ground floor. The columns represent the rooms on each floor.The manager $($the user$)$ will be presented with a menu that will allow him$/$her to do the following:Add occupant$($s$)$ to a room.Remove occupant$($s$)$ from a room.Determine if a room is occupied and with how many occupants. Display the hotel room set up$.$Quit the program.The program will utilize functions as defined by the following prototypes and described after I describe the main function. The prototypes need to be placed above the main with the actual functions defined below the main.void initHotel$($int hotel$[][5)$;int menu$()$;void processChoice$($int hotel$[][5],$ int choice$)$; void checkRoomOccupancy$($int hotel$[][5])$;void addOccupant$($int hotel$[][5])$;Choice $=1$: Call thetwo$-$D parameter.Choice $=2$: Call thethe two$-$D parameter.COP $2220$ Exam $2$ Spring $2024$ void removeOccupant$($int hotel$[][5])$; void displayHotelSetup$($int hotel$[][5])$;The algorithm for the main function follows: $($Pay attention to indentation in the algorithm.$)$Declare a two$-$d array named hotel with $3$ rows and $5$ columns.Call the initHotel function and give it the hotel array as a parameter.Do:While the user's choice is not equal to whatever your quitting value is$.$The description of the initHotel function follows:Go through the two$-$D array parameter in row major order andassign $0$ to each element of the array.
