[SOLVED] Oop244 workshop 7: derived classes & custom i/o operators

In this workshop, you will work with classes that make up the hierarchical structure. The base or parent class will be a `MotorVehicle` that holds common attributes of a vehicle with an engine then the child class `Truck` will be derived from the parent class.In addition to this hierarchy, we will define custom input/output operators for these classes.## Learning OutcomesUpon successful completion of this workshop, you will have demonstrated the abilities to: inherit a derived class from a base class
shadow a base class member function with a derived class member function
access a shadowed member function that is defined in a base class
utilize custom input/output operators with these classes
describe to your instructor what you have learned in completing this workshop## Submission PolicyThe workshop is divided into one coding part and one non-coding part: Part 1: worth 100% of the workshops total mark, is due on **Thursday at 23:59:59** of the week of your scheduled lab.
Part 2 (reflection): non-coding part, is due on **Sunday at 23:59:59** of the week of your scheduled lab. The reflection doesnt have marks associated with it but can incur a **penalty of max 40% of the whole workshops mark** if your professor deems it insufficient (you make your marks from the code, but you can lose some on the reflection).**The code that is submitted late receives 0%.** On Sunday at midnight the submission closes; if the workshop is incomplete when the submission closes (missing at least one of the coding or non-coding parts), **the mark for the entire workshop is 0%**.Every file that you submit must contain (as a comment) at the top **your name**, **your Seneca email**, **Seneca Employee ID** and the **date** when you completed the work.If the file contains only your work or work provided to you by your professor, add the following message as a comment at the top of the file:> I have done all the coding by myself and only copied the code that my professor provided to complete my workshops and assignments.If the file contains work that is not yours (you found it online or somebody provided it to you), **write exactly which part of the assignment is given to you as help, who gave it to you, or which source you received it from.** By doing this you will only lose the price for the parts you got help for, and the person helping you will be clear of any wrongdoing.## Compiling and Testing Your ProgramAll your code should be compiled using this command on `matrix`:`bash
g++ -Wall -std=c++11 -g -o ws file1.cpp file2.cpp
` `-Wall`: compiler will report all warnings
`-std=c++11`: the code will be compiled using the C++11 standard
`-g`: the executable file will contain debugging symbols, allowing *valgrind* to create better reports
`-o ws`: the compiled application will be named `ws`After compiling and testing your code, run your program as following to check for possible memory leaks (assuming your executable name is `ws`):`bash
valgrind ws
`To check the output, use a program that can compare text files. Search online for such a program for your platform, or use *diff* available on `matrix`.> Note: All the code written in workshops and the project must be implemented in the **sdds** namespace.# lab (part 1) (100%)## `MotorVehicle` ModuleDesign and code a class named `MotorVehicle` that holds information about a vehicle with an engine. Place your class definition in a header file named `MotorVehicle.h` and your function definitions in an implementation file named `MotorVehicle.cpp`.Include in your solution all of the statements necessary for your code to compile under a standard C++ compiler and within the `sdds` namespace.### `MotorVehicle` ClassDesign and code a class named `MotorVehicle` that holds information about a vehicle with an engine.#### `MotorVehicle` Private MembersThe class should be able to store the following data: a license plate number as a statically allocated array of characters of size 9.
the address where the vehicle is at a given moment as a statically allocated array of characters of size 64.
the year when the vehicle was built.You can add any other private members in the class, as required by your design.#### `MotorVehicle` Public Members a custom constructor that receives as parameters the license plate number and the year when the vehicle was built. Set the location of the vehicle at `Factory`. Assume all data is valid.
`void moveTo(const char* address)`: moves the vehicle to the new address if the new address is different from the current address. Prints to the screen the message
`txt
|[LICENSE_PLATE]| |[CURRENT_ADDRESS] > [NEW_ADDRESS]|<ENDL>
`
where
the license plate is a field of 8 characters aligned to the right
current address is a field of 20 characters aligned to the right
new address is a field of 20 characters aligned to left `ostream& write(ostream& os)`: a query that inserts into `os` the content of the object in the format
`txt
| [YEAR] | [PLATE] | [ADDRESS]
`
`istream& read(istream& in)`: a mutator that reads from the stream `in` the data for the current object

Current location: [USER TYPES HERE]
`#### Helper Functions overload the insertion and extraction operators to insert a `MotorVehicle` into a stream and extract a `MotorVehicle` from a stream. These operators should call the `write`/`read` member functions in the class `MotorVehicle`.## `Truck` ModuleDesign and code a class named `Truck` that holds information about a motor vehicle that can carry cargo. Place your class definition in a header file named `Truck.h` and your function definitions in an implementation file named `Truck.cpp`.Include in your solution all of the statements necessary for your code to compile under a standard C++ compiler and within the `sdds` namespace.### `Truck` ClassDesign and code a class named `Truck` that holds information about a motor vehicle that can carry cargo. **This class should inherit from `MotorVehicle` class.**#### `Truck` Private MembersThe class should be able to store the following data (on top of data coming from the parent class): a capacity in kilograms as a floating-point number in double precision; this is the maximum weight of the cargo the truck can carry.
the current cargo load (in kilograms) is a floating-point number in double precision; the load cannot exceed the capacity.You can add any other private members in the class, as required by your design. **Do not duplicate members from the base class!**#### `Truck` Public Members a custom constructor that receives as parameters the license plate number, the year when the truck was built, the capacity of the truck and the current address. Call the constructor from the base class and pass the license number and year to it. Set the current cargo to 0 and move the truck to the address specified in the last parameter.
`bool addCargo(double cargo)`: a mutator that adds to the attribute that stores the current cargo load the weight specified as a parameter. **Do not exceed the capacity!** If the current load has been changed, return `true`, otherwise return `false`.
`bool unloadCargo()`: a mutator that unloads current cargo (sets the attribute to 0). If the current load has been changed, return `true`, otherwise, return `false`.
`ostream& write(ostream& os)`: a query that inserts into `os` the content of the object in the format
`txt
| [YEAR] | [PLATE] | [ADDRESS] | [CURRENT_CARGO]/[CAPACITY]
`
`istream& read(istream& in)`: a mutator that reads from the stream `in` the data for the current object
