Client Requirements
The local painting and decorating require a program to estimate the cost of painting a single room. The decorator needs to enter the height of the room (assume all walls are the same height i.e. no sloping ceilings). The height of the walls must be entered (minimum 2.4m and maximum 6m), the length of all four walls must be entered (minimum 1m and maximum 25m). The program then needs to calculate the total area of the wall(s) to be painted.

The program should allow for a choice of three paints:

• Luxury quality which costs £1.75 per square metre
• Standard quality which costs £1.00 per square metre
• Economy quality which costs £0.80 per square metre
• The decorator should also be able to choose an undercoat if required,
this costs an additional £0.45 per square metre.

The program must have and display:

• A well designed interface
• Working calculation to determine the area to be painted
• an itemised bill with a total amount and invoice number
• look like an invoice that can be handed to a customer
