Program :- 1

A Hospital wants to create a database regarding its indoor patients. The information to store include 

a) Name of the Patient
b) Date of Admission
c) Disease
d) Date of Discharge

Create a structure to store the date (year, month and date as its members). Create a base class to store the above information. The member function should include functions to enter information and display a list of all the patients in the database. Create a derived class to store the age of the patients. List the information about all the to store thje age of the patients. List the information about all the pediatric patients(less than twelve years in age)

Program :- 2

Write a program that creates a binary file by reading the data for the students from the terminal. The data of each student consist of roll no., name ( a string of 30 or lesser no. of characters ) and marks. 

Program :- 3

Make a class Employee with a name and salary. Make a class Manager inherit from Employee. Add an instance variable, named department, of type string. Supply a method to tostring that prints the manager's name, Department and salary. Make a classs Executive inherit from Manger. Supply a method to string that prints the string "executive " followed by information stored in the manager superclass object. Supply a test program that tests these classes and methods. 

Program :- 4

Imagine a tollbooth with a class called toll booth. The two data items are of type unsigned int to hold the total number of cars, and a type double to hold the total amount of money collected. A constructor initializes both these to 0. A member functions called payingcar() increments the car total and adds 0. 50 to the cash total. Another function, called nopaycar(), increments the car total but adds nothing to the cash total. Finallu a member function called displays the two totals. 

Include a program to test this class. This program should allow the user to push one key to count a nopaycar. Pushing the ESZ key should cause the program to printout the total cars and total cash and then exit. 

Program :- 5

Write a function called reversit() that reverses a string (an array of char ). Use a for loop that swaps the first and last characters, then the second and next to lastcharacters and so on. The string should be passed to reversit() as an argument. 

Write a program to exercise reversit(). The program should get a string from the usre, call reversit(), and print out the result. Use an input method trhat allows the embedded blanks. Test the program with Napoleons famous phrase, "Able was I ere I Saw Elba)". 

Program :- 6

Assume that a bank maintains two kinds of accounts for customers, one called as savings account and other as current account. The savings account provides compound interest and withdrawl facilities but no cheque book facility. The current account provides cheque book facility but no interest. Current account holders should also maintain a minimum balance and if the balance falls below this level, a service charge is imposed. 

Create a class account that stores customer name, account number and type of account. From this derive class es curr_acct and sav_acct to make them more

specific to their requirements. 

Include necessary member functions in order to achieve the following tasks:

a) Accept deposit from a customer and update the balance

b) Display the balance

c) Compute and deposit interest. 

d) Permit Withdrawal and update the balance

e) Check for the minimum balance, impose penalty, necessary and update the balance. 

f) Do not use any constructors. Use member functions to initializes the class members. 

Program :- 7

Create a base shape. Use this class to store two double type values that could be used to compute the area of figures. Derive two specific classes called triangle and rectangle 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 three classes, design a program that will accept dimensions of a triangle or a rectangle interactively and display the area. 

Remember 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
