Hello, everyone. I need help with a C++ assignment.

Topics:

Introduction to classes (continued)

Overloading function names

Abstract data types

Friend functions

Overloading operators

(Each function except main should have a function header similar to this

example:)

/* ******************** getSize ********************

asks user for size

size is saved in calling function via reference parameter

*/

The assignment requires me to change a previous code I wrote for a previous assignment. Here is that code:

"

#include #include #include #include

using namespace std;

/*

********************setUpCar********************

*/

class Car { public:

char reportingMark[5]; int carNumber; string kind; bool loaded; string destination; };

void input(Car *T); void output(Car *T);

int main () { Car *T = new Car;

input(T); output(T);

delete T;

return 0; }

/*

******************** inputFunction ********************

*/ void input(Car *T) { string str, s;

cout << " Enter the reporting mark as a 5 or less character uppercase string: "; cin >> str;

for (int i = 0; i < str.length(); i++) T->reportingMark[i] = toupper(str[i]);

cout << " Enter the car number: "; cin >> T->carNumber; cout << " Enter the kind: "; cin >> T->kind; cout << " Enter the loaded status as true or false: "; cin >> s;

istringstream(s) >> boolalpha >> T->loaded; if (T->loaded == true) { cout << " Enter the destination: "; cin.ignore(); getline(cin, T->destination); } else T->destination = "NONE"; }

/*

******************** outputFunction ********************

*/

void output(Car *T) { //print the results cout << " Reporting Mark: " << T->reportingMark; cout << " Car Number: " << T->carNumber; cout << " Kind: " << T->kind; cout << " Loaded Status: " << boolalpha << T->loaded; cout << " Destination: " << T->destination << " "; } "

Now, here is the assignment:

Problem 3.1:

Copy the solution from problem 2.2 (code above)

Make the following additions and changes:

1. Arrange the functions in the order:

* main

* output

* setUp (was setUpCar)

* input

2. Change the output function so it is a member function of the class Car.

3. Change the name of the setUpCar function to setUp and make it a member function of the class Car, with five parameters specified as constant reference parameters.

4. Make all the data in the Car class private and make the member functions public.

5. Do NOT make the input function a member function.

6. Change the parameters of the input function to five reference parameters corresponding to the five fields in the class.

7. In main define five variables. Pass these variables to the input function so the input function can set their values.

8. In main define a Car object. This time the Car object will be in the stack for main, rather than in the heap. Name this object car1.

9. In main call the setUp function and pass the five variables, rather than calling it from the input function.

10. In main call the output function.

11. Test the program with the same data as was used in assignment 2.

Problem 3.2:

Copy the solution from problem 3.1

Make the following additions and changes:

1. Build three constructors and a destructor for your Car class:

* A constructor that accepts five constant reference parameters. Build this constructor with only one line of code that calls the setUp member function.

* A copy constructor.

* A default constructor that sets the following values:

reportingMark	(an empty string)
carNumber	0
kind	other
loaded	false
destination	NONE

* A destructor that does nothing, basically a stub.

2. Arrange the constructors and destructor in the class before the other member functions in the order:

default constructor, copy constructor, constructor that takes five constant reference parameters, destructor

3. Arrange the function definitions in the same order.

4. Remove the call to the setUp function from the main function.

5. Revise the main function to create three Car objects in the stack:

6. car1 with the same values used in assignment B.

7. car2 which is a copy of car1.

8. car3 which is created with the default constructor.

Now, add code in the main function to print these headings and use the Car member function to print the data for each of the three cars:

Contents of car1:

reportingMark:	SP
carNumber:	34567
kind:	box
loaded:	true
destination:	Salt Lake City

Contents of car2:

reportingMark:	SP
carNumber:	34567
kind:	box
loaded:	true
destination:	Salt Lake City

Contents of car3:

reportingMark:
carNumber:	0
kind:	other
loaded:	false
destination:	NONE

Problem 3.3

Copy the solution from problem 3.2

Create a friend function for the function operator== which tests to see

if two objects are equivalent. The two objects are equivalent if they

have the same reportingMark and number (do not look at the kind, loaded, and destination fields).

Test with the following code in main:

if (car1 == car2)

cout << "car1 is the same car as car2 ";

else

cout << "car1 is not the same car as car2 ";

if (car2 == car3)

cout << "car2 is the same car as car3 ";

else

cout << "car2 is not the same car as car3 ";
