========================================================================

10=> Create two classes DM and DB which store the value ofdistances. DM stores distances in meters and centimeters and DB in feet andinches. Write a program that can read values for the class objects and add oneobject of DM with another object of DB. Use a friend function to carry out theaddition operation. The object stores the results may a DM object or DBobject, depending on the units in which the results are required. The displayshould be in the format of feet and inches or meters and centimeters dependingon the object on display.  (1 Feet = 0.3048Meter,  1Meter = 3.28 Feet,  1Inch = 2.54 Centimeter,  1Centimeter = 0.3937 Inch)

========================================================================

11=> Define Operator overloading. Create class Time that has three data members hour, minute and second and two constructor, default constructor and parameterized constructor to initialize data member. Write a program to add two times by overloading operator +

======================================================================= 

 12=> Define a class Time with hours and minutes as two data members, addnecessary member functions to initialize and display data of class. Do not useconstructors in a class. Define a member function sum() which adds two Timeobjects. Invoke the statements like T3.sum(T1, T2) in main ()

=======================================================================

13=> Define a class matrix with an integer array of 3X3 as a data member. Define a friend function which adds two matrix objects and returns resultant matrix object.

=======================================================================

14=> Define a class complex with real and imaginary as two data member, addnecessary constructors and member function to initialize and display data ofclass. Class should overload the + operator to add two complex objects andreturn the results. Invoke the statements like C3=C1+C2 in main () 

=======================================================================

=======================================================================

17=> Write a C++ program to explain Objects as function arguments. Define a class name VALUE with two data member variable, two member functions for inputting data and displaying the result. Define third member function that takes two objects as arguments and adds the objects

========================================================================

18=> Write a program in C++ to generate Fibonacci series by using recursion

=======================================================================

 19=> Declare a class called my string having char * ptr_str as a member, used to point to a string. define a constructor for initializing members. define an overloaded operator + to be applied on two operand of type class my_string for concating string pointed by str_ptr of operand. the resultant string is placed in a new object of type class my_string which is returned. define main to show the usage of these functions

========================================================================

20=> Consider a class network as shown in figure given below. The class Employee derives information from both Account and Admin classes which in turn derive information from the class Person. Define all the four classes and write a program to create, update and display the information contained in Employee objects

========================================================================

21=> The class Result derives information from the classes Internal, University and External respectively. The Internal and External classes access information from the Student class. Define all five classes and write a suitable program to create and display the information contained in Result object

22=> Declare a class called logic_gate to represent logic gates. The class has three data members - input1, input2 and input3 to represent three inputs to the logic gate. The class also has a virtual function member called get_gate_output. Derive two classes from the base class logic_gate, namely, and_gate and or_gate to represent ‘logical and gate’ and ‘logical or gate’ respectively. Define function get_gate_output in both of these classes to get the output of the gate. Show use of above classes.
