After completing the Programming Challenge $5-9$ in the book, create $5-9m$ by modifying the original $5-9$ to use a file named Occupancy.txt as input.

a$.$ The first line and field on the file is the floor count.

b$.$ Subsequent lines contain the number of rooms and rooms occupied counts.

c$.$ This file should be copied into the same folder as the $5-9m.$cpp file in your solution folder.

All outputs to the screen should be mirrored to an output file named HotelReport.txt$.$

a$.$ This file will be found in the same folder as the $5-9$m$.$cpp file in your solution folder.

For failed validations, issue a message to describe the validation error and

a$.$ Return with return code $10$ if file fails to open

i$.$ This is written as: return $10$;

b$.$ Return with return code $12$ if fail to read number of floors $($e$.$g$.$ empty file$).$

c$.$ Return with return code $14$ of number of floors is invalid

d$.$ For floor related validations, issue a continue statement to skip further processing for that floor.

You may expect that the input file has the two input counts for each floor.
