Create a problem in C++: Design a program that will read in 2 files (“Cars.txt”

Question

Create a problem in C++:

Design a program that will read in 2 files (“Cars.txt” and “detailReport.txt”) and then will print out the output that correspond to the car’s details giving in “detailReport.txt'

Here is a general skeleton of what you should have:
(Note: you can use string and vector for the program)

- A Structure ErrorList that have 2 variables errorCode (int) and errorMessage (string);

- A Class Car that have 4 private variables (name (string), errorSize (int); error (int *), numOfCar (static int)). (You have to make error a int* since each car have random amount of error and depend on errorSize). You need atleast constructor, destructor, mutators and accessors (get and set for each variable). You can add more functions if it need be.

- In main()

Read in “detailReport.txt” to an array of ErrorList.

Read in “Cars.txt” into an array of Car.

Once you have all the data into correct places in the program, do exceptional handling to print out each car with its errors (and throw “Car is in good shape” if Error is 0).

Tips:
When you read “Cars.txt” into program, be careful how you handle the numbers of errors for each car. Since each car have random amount of errors, if you just use a loop to read, it might crash your program; therefore you could read in as a string of words, then split the string into array of vector. After that set each element of the vector into correct location.

Explanation / Answer

The following code has not been tested in runtime due to lack of time but it doesn't contain any compilation error. Following assumptions are made for this code:

detailReport.txt looks like :

1 errordefinition1

2 errordefinition2

and Cars.txt looks like:

Mustang 1 2

BMW 2

O/p will look like

Mustang:

errordefinition1

errordefinition2

BMW:

errordefinition2

In case of any doubt please comment on the answer.
