Question

Complete the following task in C++. Separate your class into header and cpp files. You can only use iostream, string and sstream. Create a main.cpp file to test your code thoroughly.

Given : commodity.h and commodity.cpp here -> https://www.chegg.com/homework-help/questions-and-answers/31-commodity-request-presented-two-diagrams-depicting-commodity-request-classes-form-basic-q39578118?trackid=uF_YZqoK

Given : locomotive.h, locomotive.cpp, main.cpp -> https://www.chegg.com/homework-help/questions-and-answers/complete-following-task-c--separate-class-header-cpp-files-useiostream-string-sstream-crea-q39733428

Create : DieselElectric.cpp DieselElectric.h

DieselElectric

dieselElectric

-fuelSupply:int

---------------------------

+getSupply():int

+setSupply(s:int):void

+dieselElectric(f:int)

+~dieselElectric()

+generateID():string

+calculateRange():double

The class variables are as follows:

fuelSuppply: The fuel supply of the train in terms of a number of kilolitres of diesel

fuel.

The class methods are as follows:

Getter and Setter: The getter and setter for the sundry class variable.

dieselElectric(f:int): The constructor for the class. It should instantiate the class

based on the given parameters.

dieselElectric(): The destructor for the class. It should deallocate any memory

assigned to the class. Additionally, it should (as the rst thing it does) print "Diesel

Electric Train: Name" with a newline at the end. Name" in this case refers to the

train's name assigned to it.

generateID(): This function generates a unique ID for the train by producing a

string that has the following structure:

- The start of the string is the type of train.

- Append the first 3 letters from the first commodity

-Append the total tonnage carried by the train to the end

Each should be separated by a "-" So for example,

dieselElectric-Coa-1000

You can assume there will be at least one commodity when this function is called.

calculateRange(): This calculates and returns the range of the train using the fol-

lowing equation:

Range=(fuelSupply *3.5)- 5*(avgTonsPerCar)

If the range is negative, then the range should be set to 0. The average tons per car

only considers the current number of cars and tons associated with those cars.
