- There are two types of data members in a class: static and non-static. Give an example of real-world use for a static data member.Program SpecificationUsing python, design a class named PersonData with the following member variables: lastName firstName address city state zip phone Write the appropriate accessor and mutator functions for these member variables. Next, design a class named CustomerData , which is derived from the PersonData class. The CustomerData class should have the following member variables: customerNumber mailingList The customerNumber variable will be used to hold a unique integer for each customer. The mailingList variable should be a bool . It will be set to true if the customer wishes to be on a mailing list, or false if the customer does not wish to be on a mail-ing list. Write appropriate accessor and mutator functions for these member variables. Next write a program which demonstrates an object of the CustomerData class in a program. Your program MUST use exception handling. You can choose how to implement the exception handling. Start your program with a welcome message Make sure…In C++

- Write C++ code for a class named MuniBus that has the following private member variables: int totalPassengers; double faresCollected; and the following public member functions: void passengerBoard() - adds 2.50 to faresCollected and adds 1 to totalPassengers double getFaresCollected() - returns faresCollected int getPassengers() - returns totalPassengers void reset() - sets totalPassengers and faresCollected to zero MuniBus() - default constructor. Initializes both totalPassengers and faresCollected to 0 MuniBus(int tp, double fc) - constructor which initializes totalPassengers to tp, faresCollected to fc ~MuniBus() - destructor. Prints out a message saying that the bus is being destroyed, and also prints out totalPassengers and faresCollected. Write the class declaration and implement all of the constructors, the destructor, and member functions. You do not need to demonstrate using your class or show output.The following class definitions and function definitions should be used to help you finish the exam. train.h: car.h: #ifndef CAR_H #define CAR_H using namespace std; class Car #include "car.h" using namespace std; #ifndef TRAIN_H #define TRAIN_H class Train { private: Car* tHead; Car* tTail; public: Train(); -Train(); void addcarBack(Car *); void deleteFirstcar(); void removeFirstcaróftype(const string &); { private: string name; double maxSpeed; public: Car* nextcar; public: car(); Car(string); double getMaxspeed () const; string getName() const; void setName(const string &); }; #endif // Display list car by car void display() const; }; #endif Part of train.cpp: // addcarBack logic: if (traincarsHead == 0) { traincarsHead = toAdd; traincarsTail = toAdd; else { traincarstail->nextcar = toAdd; traincarsTail = toAdd;Using C# language: Programming PLO-2 Measured: Design, implement, and evaluate computer solutions utilizing structured and object-oriented programming methodologies. Design a class named Contractor. The class should keep the following information: Contractor name Contractor number Contractor start date Write one or more constructors and the appropriate accessor and mutator functions for the class.
