Group Instructions
This program will be a GROUP project. Each group will need at least 3 students in it. I will form your groups by randomly selecting students from Canvas class list.

Each group member will be responsible for writing the solution to the program using stubs and drivers for the functions other members are responsible for and submitting that solution for themselves. In addition, the group will be responsible for putting together all the individual parts and turning that in as a combined group solution. See below for explanation of each individual group member’s responsibilities.

Every member will: write main() and getShipData(). Create stubs for functions written by other members as needed. Stubs should display the headers of each report section ONLY. Place documentation header on each function/stub. For the functions you are writing use drivers to test your code.

Member 1: in addition to main() and getShipData() write showShipCategories() and getCategory()
Member 2: in addition to main() and getShipData() write showShipCapacity() and getAveCapacity() Member 3: in addition to main() and getShipData() write showShipSpeed() and getHighestSpeed()
Mandatory Portion Instructions
The Royal Caribbean cruise line would like a report on all their ships. Given the ship name and other data, write a C++ program to print a report showing the information described below.


You will need several arrays to store all the ship data. You should reserve space for 30 ships in your arrays. Sample line from the data file is shown below. Assume data file will NOT have more than 30 lines of data but it could have less.

Freedom 3634 160000 21

Your main() should call the functions described below. Each function should have a function documentation header. Hierarchy of the program:




1. Write a function, getShipData(), to read in the ship data from the file fleet.dat and store it in four arrays, one for the ship names, one for the capacity, one for the tonnage and one for the speed. Put the data for the first ship in element 0 in each array, the data for the second ship in element 1 of each array, etc. Return the actual number of ships read to the caller. Pass all arrays as parameters to this function. Close the data file.

NOTE: All further processing of the data will be done with the data stored in the arrays, not the data file.

2. Write a function, showShipCategories(), to show the ship data stored in the arrays in the console window. Include a title for the report and a line with column headings for the ship type/category, ship name, capacity, gross tonnage and top cruising speed. For each ship print the ship type/category (see table in part 3), ship name, capacity, tonnage and speed. Call function in step 3 to assign ship category to a ship.

3. Write a function, getCategory(), that accepts a SINGLE ship’s gross tonnage and returns the category name according to the table below. This function DOES NOT have a loop in it!!!
Gross Tonnage Ship type/category
< 48,600 Empress Family
< 74,000 Sovereign Family
< 90,100 Vision Family
< 138,000 Radiance Family
< 155,000 Voyager Family
< 160,666 Freedom Family
> 160.666 Oasis Family


3. Write a function, getAveCapacity(), to find and return the average ship capacity for all ships. Ship data is passed via parameters.

4. Write a function, showShipCapacity(), to show the name and capacity for all ships with a capacity greater than the average. Insert a few blank lines to separate this part of the report from the previously printed data. Then print a title ("Ships with Above Average Capacity "), underneath the title print the average capacity found by the previous function ("Average Capacity = 999999.9") followed by a line with column headings for the ship name and capacity. Then list the name and capacities for each ship with capacity above the average.

5. Write a function, getHighestSpeed(), to find and return the array index for a ship with the highest cruising speed.

6. Write a function, showShipSpeed(), that will display the name(s) and cruising speed of ship(s) with the highest cruising speed.


* READ* THIS: Naming of projects:

Individual member solution: Last_Program6_MemberX – where X is your member number (1,2,3, etc.)

Combined solution should be named: Combined_LastMember1_LastMember2_LastMember3

Example:
Group members:

Brown – member 1, Gray – member 2, Black – member 3

Brown_Program6_Member1
Gray_Program6_Member2
Black_Program6_Member3

Combined_Brown_Gray_Black



1. Declare all variables and constants that your program uses at the beginning of your program.
2. Your program should include two types of comments: Header Comments at the top including lines with:
- Your name, course name, and class time
- A sentence or two explaining the purpose of the program
- A description of the input data needed by the program when you run it
- A description of the processing (calculations) done by the program
- A description of the results (output) produced by the program
b. In-line comments: There should be an in-line comment for each main step in your program. In general, this means a comment with each group of C++ statements that handles the input, the processing and the output steps of your program.
3. Use meaningful identifier names
4. Include clear prompts for the user about entering the data.
5. Include clear descriptions of the results when you display them.
What to turn in?
1. Log into Canvas, locate this assignment, and upload the compressed project folders.
2. Upload the grade sheet (Word document) after you have edited it to provide requested information.
3. You’re done.
