Question

In c++, please make it short and simple

A hotel chain needs a program which will produce statistics for the hotels it owns.

Write a program which displays the occupancy rate and other statistics for any of the chain’s large hotels (all are 20 floors with 16 rooms each floor).

In main:

-declare a 20 X 16 array of “int” named hotel to represent a hotel’s 20 floors and 16 rooms per floor.

Then in main, repeatedly:

-call a function which fills the hotel array with 1s and 0s, where 1 indicates an occupied room and 0 indicates an unoccupied room. Call a second function to validate that each entry is either 1 or 0 by having the second function access the original entry using a pointer in its parameter list.

-pass the hotel array to a third function which dynamically allocates a new size 20 “int” array with each element representing a floor of the hotel and the floor’s number of occupied rooms; place the number of occupied rooms of each floor into the new array and return it to main.

-display the floor number** and number of occupied rooms on each floor by incrementing the address of the new array.

-also calculate and display the hotel’s overall occupancy rate to 1 decimal (total rooms occupied per total rooms), and the floor number** and number of occupied rooms of the floor with the highest occupancy.

-process another hotel (unknown number of hotels in chain).

**NOTE: hotels do not have a floor numbered 13 due to guests’ superstitions.

To create your screen print, temporarily set the floors and rooms to 3 and 5 respectively to reduce data entry, and enter:

Floor #1: occupied, occupied, unoccupied, occupied, unoccupied

Floor #2: occupied, unoccupied, occupied, occupied, occupied

Floor #3: occupied, unoccupied, unoccupied, unoccupied, occupied
