A hotel has three floors numbered 0 to 2 (floor 0 is the ground floor). There are 15 rooms on each floor. The hotel gets many enquiries from customers to check if a room is available that day. The availability data for that day is stored in a 2D array Version1

The first index is the floor number.
The second index is the room number.
On each of the three floors, the room numbers are 1 to 15.

Each cell of the array stores either:

'A' – the room is available
'B' – the room is already booked.

Write the declaration statement for the 2D array Version1

An enquiry program will:

input a floor number
output all room numbers that are available on that floor
output the number of rooms that are available.

The output must be in the format shown in the two examples. A wheelchair user makes an enquiry. She requires a room on the ground floor only. Example program outputs:

text

01Floor number: 0020 room(s) available

There are no available rooms on the ground floor.

text

01Floor number: 00270311042 room(s) available

Shows two rooms available on the ground floor: rooms 7 and 11. Write pseudocode for this enquiry program.

Customers are becoming more selective with their enquiries when searching for an available room. A new program design is required. It will create a record to define the data for a room. Each room:

may have a sea view
is classified as: single room ('S'), double room ('D') or family room ('F')
is either standard ('ST') or deluxe ('DL').

Complete the pseudocode.

The room data is stored in a 2D array Version2 of type RoomData The new enquiry program uses this new data design and will:

input the three customer requirements
output the floor number(s) and room number(s) for all matching available rooms.

Example program output:

text

01Room type - S/D/F ?    F02View - True/False ?    False03Room grade - ST/DL ?   DL0405Matching floor number and room number:060    4070    5

The customer asks for a deluxe family room; no need for a sea view. The new enquiry program has found two matching rooms on the ground floor. Write pseudocode for the new enquiry program.
