Part II:

PA3: Car Dealership (40 points)

For Programming Assignment 3 you will be creating a program to

manage cars in a dealership.

This will again be a menu driven system.

You will make a

vector

of Dealers (there can be zero to

many dealers). Each dealer can have zero to many cars on the lot, represented not by a vector,

but by a

dynamic array

.

The following is your menu:

1.

Read

Dealers and Cars

from file

2.

Displ

ay Dealers

3.

Choose a Dealer Number, D

isplay Cars

4.

Choose a Dealer Number, Add Car

5.

Choose a Dealer Number, List Cars and Modify a Car

6.

Choose a Dealer, Sort cars

by VIN

(EXTRA CREDIT)

7.

Write Dealers and Cars

to file

(EXTRA CREDIT)

Your program will be

object oriented

(using classes

, not stru

cts

)

with the following classes

defined in Dealer.h and Car.h

You will have four files for your program (Use these file names!): main.cpp, functions.h,

Dealer.h, Dealer

.cpp. Place into a file folder named LastnamePA3, the

n

zip the

content and hand

in a zip file to canvas

main.cpp: this will be your driver file

.

functions.

h: this will contain your

functi

ons for each of the menu items

.

Dealer

.h: this will contain the class declarations for

car

and dealer

including the operator

<<

.

Dealer

.cpp: this will contain the class implementations for

car

and dealer.

Remember,

you do not #include Dealer.cpp, just #include functions.h and #include

Dealer.h

You will be storing your

dealer

objects in a

vector

. In the main function, you will create a vector

of

Dealers

. When the menu

is

called, you will have to check your vector and ensure that

it is not

empty

(size == 0)

before referring to the index number

of the vector.

Your Dealer vector points

to a

dynamic array

of

car

s

(remember dynamic arrays use the

keyword new)

.

W

hen you access

the

car

s class you should verify that it is not set to nullptr

before accessing it

.

You

may not use

any global variables

, so must pass vectors and arrays into parameters. If you

want to change a vector you must pass by reference (&). If you have arrays, y

ou must pass size

and the array, but arrays are already pointers, so do not use & when passing an array

.

Each menu item will have a corresponding function, and the definition of the function will be

found in the file functions.h.

Also, your operator << fun

ction for Dealer and Car will be

implemented in your functions.h.

All input/output

will be done in the functions and not in main

(ex

cept

asking for what menu option the user wants).

The following are the details for each of your menu options:

1.

Read

Dealers and Cars

from file

2.

3.

Choose a Dealer Number, Display Car

4.

1.

Pass the vector of dealers (from main) into the function by reference.

Each

Dealer will

have a name and number followed by the number of cars in the dealership (on separate

lines). Then you will read in a Vin, Make, Model, Year and Price for each car (on

separate lines). You can assume that the number of cars as well as the Vin

, Make,

Model, Year and Price will be complete for each car. Each dealer can have

format will be as follows

:

Dealer Name

Dont forget, between << and a getline you must use a .ignore( ) (e.g. infile.ignore( ) )

2.

Pass the vector of dealers (from main) into the function by reference.

Display the Dealer Name

and

Number for each dealer (put a blank line between dealers)

. Use the << operator with cout

(cout << dealer[x];)

3.

Pass the vector of dealers (from main) into the function by reference.

Display the

Dealer

Names and Numbers (menu #2). Ask the user for the de

aler number, display all of the cars

by

using a for loop (from zero to size of the car array)

using the << operator with cout

( cout <<

dealer[x].

carArrayPtr[x];)

4.

Pass the vector of dealers (from main) into the function by reference.

a)

D

isplay the Dea

ler

Names and Numbers (menu #2).

b

)

Ask the user for

the dealer number then the new

car

information

.

Follow the steps found in CSCI 1411 Lab 09 to increase the dynamic array

.

(Essentially you will make a new array, one bigger than

the previous car array.

Then you will

copy everything over from the old car array to the new one. Then you will point the car pointer

to the new array)

You can earn

up to

20%

extra credit

(48/40)

for completing 5 and 6 as long as you get at least

80% on the required tasks.

5.

Pass the vector of dealers (from main) into the function by reference.

D

isplay the Dealer

Names and Numbers (menu #2).

6.

Ask the user for the dealer number. Sort the cars by vin and

display them (with blank lines between each car

)

6.

Pass the vector of de

alers (from main) into the function by reference. Also pass in the

filestream (from main) by reference

. Call the output file out.txt

.

Write all of the Dealers and

Cars to a

separate

output file

in the same format as in item #1

. This should include all ch

anges to

the vector and dynamic array (including add, delete, modify, sorting etc.)

What to Hand

-

In:

Submit to canvas main.cpp, functions.h, Dealer.h and Dealer.cpp and an in.txt files. Each must be

complete with your name on i

t. If you complete the extra credit, you must have 7 menu items and this

must be documented in your main.cpp.

Note: You must document ALL code that you took from ANY source (including the internet, your book,

someone else). Failure to do so may result in a

grade of zero for EACH student

with too similar code

.

You can work together with big ideas, but all code MUST be your own.
