Write a class and member functions for a class complex as follows

Class complex

{

    Int re, img;

     public:

    complex (int =0,int=0);

    complex(complex &);

    void accept();

    void display();

Write necessary class and member function definitions for a cricket player object. (Use array of objects).

The program should accept details from user (max 10) : player code, name, runs, Innings, played, number of times not out.

The program should contain following menu:-

 Enter details of players.

 Display average runs of a single player.

Average runs of all players

Create a C++ class mydate with three members dd,mm,yy. Write a menu driven Program with the following options. -Increment date by 1 day. -Subtract 2 days from date. (Use function overloading ).

Create a base class called Shape. Use this class to store two double values that could be used to compute the area of figures. Derive three classes called as triangle, rectangle and circle from the base Shape. Add to the base class a member function get_data() to initialize base class data members and another member function display_area() to compute and display the area of figures. Make display_area() as a virtual function and redefine this function in the derived classes to suit their requirements. Using these four classes, design a program that will accept, dimensions of a triangle and rectangle and radius of circle, and display the area.The two values given as input will be treated as lengths of two sides in the case of rectangles and as base and height in the case of triangles and used as follows : Area of rectangle = x * y Area of triangle = ½ * x * y

Husna Dental is a personal dental clinic that recently operated on 1st January 2015. The payment for

dentistry services at Husna Dental is different based on the type of treatment and patient status.

Types of Treatment and Price

Patient Status Restoration(1) Extraction(2) Scaling(3)

Adult(A) RM7.50 RM18.00 RM5.00

Due to the opening ceremony, the discount of 20% will be given for children’s treatment and 15%

discount for adult’s treatment.

Write a C++ program that performs the following.

· Reads the patient's name, patient status, and type of treatment.

· Displays the appropriate message when the user enters an invalid status.

· Calculates the payment before and after discount.

· At the end of the program, displays receipt that contain patient’s name and her/his total

payment after discount.

Develop a code for the hierarchical inheritance for banking account,

· The Bank_ACC base class consisting of data members such as accno and name, and member functions get() and display().

· The SB_ACC derived class inherited from Bank_ACC class, consisting of data members such as roi, and member functions get() and display().

· The CUR_ACC derived class inherited from Bank_ACC class, consisting of data members such as odlimit, and member functions get() and display()
