Write a class LocalPhone that contains an attribute phone to store a local telephone number. The class contains member functions to input and display phone number. Write a child class NatPhone for national phone numbers that inherits LocPhone class. It additionally contains an attribute to store city code. It also contains member functions to input and show the city code. Write another class IntPhone for international phone numbers that inherit NatPhone class. It additionally contains an attribute to store country code. It also contains member functions to input and show the country code. Test these classes from main() by creating objects of derived classes and testing functions in a way that clear concept of multi-level Inheritance.

T/F 3. If class AParentClass has a protected instance data x, and AChildClass is a derived class ofAParentClass, then AChildClass can access x but cannot redefine x to be a different type
Consider the following inheritance hierarchy: class A{ protected: int x, y; public: int z; }; class B: private A{ private: int a, b, c; public: void set(int x, int y, int z, int a, int b, int c); }; Int main(){ Aobja; B objb; } a) If the protected Access specifier in A is changed to public, then how many members of B will be accessed in main() and how? b) Define the function set() without changing its signature as given above. c) Write a default constructor for the class B that does not have an empty parameter list. d) If the data members of A become private, then how they be initialized? e) Add a static data member in class B. Can we use this pointer with static members? If yes how?
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?

(a) Create an inheritance hierarchy of Rodent: Mouse, Gerbil, Hamster, etc. In the base class, providemethods that are common to all Rodents, and override these in the derived classes to perform differentbehaviors depending on the specific type of Rodent. Create an array of Rodent, fill it with different specific types of Rodents, and call your base-class methods to see what happens. (b) Create a Cycle class, with subclasses Unicycle, Bicycle and Tricycle. Demonstrate that an instance of eachtype can be upcast to Cycle via a ride( ) method. Using the above Cycle hierarchy, add a balance( ) methodto Unicycle and Bicycle, but not to Tricycle. Create instances of all three types and upcast them to an arrayof Cycle. Try to call balance( ) on each element of the array and observe the results. Downcast and callbalance( ) and observe what happens.

Refer to Example Code Ch 09-4: Which of the following is true with respect to A1, A2, and A3?a. A1 is a subclass of A2 and A2 is a subclass of A3b. A3 is a subclass of A2 and A2 is a subclass of A1c. A1 and A2 are both subclasses of A3d. A2 and A3 are both subclasses of A1e. A1, A2 and A3 are all subclasses of the class A
Create a class named Line: (a) Define private data members p1 and p2 as pointer to Point objects (the one we had in lectures), slope and length as double variables. (b) Define setter and getter functions. (c) Define a null-constructor that initializes numeric variables with zero and allocate dynamic memory for points and initialize them to [0,0] as well. (d) Overload a constructor that allocates memory for points, initilize them with given arguments, and calculate the slope and length. (e) Implement destructor, copy constructor and copy assignment operator. (f) Create a function called ”parallel” that takes too Line objects, returns true when given lines are parallel and returns false otherwise. (g) Overload the less than (<) and greater than (>) and equality (==) operators (compare the length). (h) Write a functions that reads lines in the format provided in the lines.txt from the file (without any change) and stores them in a vector named Lines. (i) Sort the objects of Lines…

Example 10-10 defined a class personType to store the name of a person. The member functions that we included merely print the name and set the name of a person. Redefine the class personType so that, in addition to what the existing class does, you can: Set the first name only. Set the last name only. Store and set the middle name. Check whether a given first name is the same as the first name of this person. Check whether a given last name is the same as the last name of this person.
