Question

Project 3

Objective:

The purpose of this lab project is to exposes you to using menus, selection writing precise functions and working with project leaders.

Problem Specification:

The PCCC Palace Hotel needs a program to compute and prints a statement of charges for customers.

The software designer provided you with the included C++ source and you are asked to complete the code to make a working program using the given logic. The function main () should not change at all.

Given Information:

Your input to the program consists of the customer’s name, room number, and the number of days they stayed in the hotel.

A sample input for the program would be:

The customer name please: Eddie

Room Number: 318

Number of days stayed in the Hotel: 3

Room Requirements:

This is a multi-level hotel where the room number ending with

19. are Single rooms.

20-39 are Family rooms

40-50 are Suites.

Rooms ending with a number > 50 are an error because they don’t exist.

Room Rates are defined as local constants and are for each day as follows:

1. Single room Single bed $99.99
2. Family room double bed $149.99
3. Suite $199.99

Internet Access Requirements:

a prompt to see if there was internet access such as:

Internet Accessed (Y/N): Y

options are chosen from menus to handle each of the inputs

A sample input if there was access would be:

Access

1 - Wired

2 – Not-wired (Wireless)

Enter Choice 1 or 2 : 1 (note that input may be 1, W, w, 2, N, or n)

Internet Access rates are defined as local constants and are for each day as follows:

1. Wireless $5.95
2. Wired $3.95

TV Access Requirements:

A prompt to see if there was TV access such as:

TV Used (Y/N): Y

options are chosen from menus to handle each of the inputs

A sample input if there was access would be:

TV Usage

1 - Basic Channels

2 – Cable Channels

Enter Choice 1 or 2 : b (note that input may be 1, B, b, 2, C, or c)

TV Access are defined as local constants and are for each day as follows:

1. Cable Channels $4.95
2. Basic channels $1.95

Complete the application based on the given source code to allow you to enter the information above, and prints a statement of the charges to be given to the customer when they checkout. Do not change the logic in the given source.

A sample output statement would be:

PCCC Palace Hotel

Room Number: 318

Eddie’s Billing Statement

Number of days in hotel: 3 in a Single Room

Room Charges $299.97

Internet Charges (Wireless) $17.85

Television Charges (Basic) $5.85

Total Charges $323.67

Local Taxes $45.55

Total Due $469.22

Thank you for using PCCC Palace Hotel. Hope to see you again.

Note: the above statement, report, does not reflect correct calculations.

Requirements:

• Include relevant information in the form of comments in your code as explained in the class.
• The Internet and TV usage may be denied, in that case the service would be none and the charges would be $0.00
• All the rates are defined as local constants inside the functions
• The setnet and settv functions each has a menu that displays the options to select from
• Each function returns the charges incurred for that option
• The local tax rate is 15% and is to be defined as a local constant

Grading criteria:

5 points	Your name, Date, course #, Due Date, name of the program and explanation to what the program does.
5 points	All constants are defined locally, used correctly and properly.
5 points	Appropriate and descriptive identifier names are used.
5 points	Menus are used to allow selection for each of the charge items.
5 points	iomanip features are used to format and money is printed with $ and 2 decimal spaces.
5 points	A prompt is used for Internet access and TV use.
15 points	IF statements are used properly and are clear.
5 points	An error message is printed if room number is > 50 and program is exited.
5 points	Specifications, Comments explaining every function are placed above each functions definition.
5 points	Functions are used clearly and properly to calculate each of the charged items.
5 points	Each function returns the charges to main ().
5 points	Proper headings and footings are displayed.
5 points	Invoice appearance is clear and looks nice.
10 points	Flowchart for every function, in full details, is handed-in and is correct. no pseudo-code.
10 points	Program runs correctly and performs the specified task.
5 points	Multiple test runs showing evidence of all requirements are submitted.
