Q1) Write the Code the following scenario. Write an abstract function named receivePay in interface with return type double and no parameters. Write another incomplete function, name Show with return type void and an argument of type int in that interface. Build a class with name Bill that implements the above interface. Bill class with name BillId , itemsquantity and itemsprice with proper datatypes with private access . Define two constructors,one default and other is parameterized to initialize the class members . Now receivePay has to beimplemented in such a way that its displays product of itemsquantity and itemsprice and Display function will display the BillId.Can we do same task with abstract class instead of interface? NOTE:SUBJECT:CSHARP (VISUAL PROGRAMMING)
Q2: Consider the following statements: public class YClass { private int a; private int b; public void one() { } public void two(int x, int y); { } public YClass() { } } class XClass extends YClass { private int z; public void one() { } public XClass() { } } YClass yObject; XClass xObject; Write the definition of the default constructor of YClass so that the instance variables of YClass are initialized to 0. Write the definition of the default constructor of XClass so that the instance variables of XClass are initialized to 0. Write the definition of the method two of YClass so that the instance variable a is initialized to the value of the first parameter of two and the instance variable b is initialized to the value of the second parameter of two. please I want solution :(

Using classes and arrays, the team will develop a set of functions for an online shopping system. The system is represented by the following structure: 1- Class Item having the following private attributes: (ID, name, quantity, price) and the following public methods:- Constructors (default, parameterized, and copy)- Setters & Getters- Operator overloading for the ==, +=,-=, >> and << operatorsNote that the ID member variable is not entered or read from the user. It is automatically set by the class as a serial ID starting with the first item of ID 1 and incrementing with every new object.2- Class Seller having the following private attributes: (name, email, items,maxItems), where items is a dynamic array of objects of type Item with the size maxItems. The class has the following public methods:- Constructor (parameterized)- Operator overloading for the insertion << operators- Add An Item.- This will take an Item object as a parameter:- If the item already exists…

Assignment Question : #include <iostream> using namespace std; class Animal { protected: int length, height; public: void set_values (int l, int h) { length = l; height = h; } virtual int cage_size (void) =0; }; A. Based on the above class definition, provide the derived classes below that will override the function cage_size from the base class Animal: i.Elephant, cage_size = 1.5 x length x height ii.Giraffe, cage_size = 2.5 x length x height B. Write the complete main () function that will create the object Elephant and Giraffe. Insert their length and height to calculate their cage_size. Note: A virtual function is a member function which is declared within a base class and is expected to be re-defined (overridden) by a derived class.
Given the following class definition: class employee{public: employee(); employee(string, int, double); employee(int, double); employee(string); void setData(string, int, double); void print() const; void updatePay(double); int getNumOfServiceYears() const; double getPay() const;private: string name; int numOfServiceYears; double pay;}; Create a class parttime derived from the above class that includes private members payRate and hoursWorked of type double along with a constructor and the definition of a print function that prints out all information from the base and derived class. Provide a test program that would demonstrate the working parttime class. Note: You can assume all code is stored in a single file.
