4)	Describe following terms in C++ with suitable examples. Function overloading, Inline function, Default arguments, Call by reference. (07 marks)

	Chapter 4 : CLASSES AND OBJECTS , CONSTRUCTOR & OPERATOR OVERLOADING
1)	What is the purpose of Static? Write Characteristics of Static Data Member and Static Member Function. Write a program that demonstrates the Static Data Member And static member function. (07 marks)
2)	Create a class Account. It has three data member account id, name and balance. Define function to assign value and display value. Define function that search account number given by the user. If account number exists, print detail of that account. Write a program using array of object. Declare at least 5 account and print details. (07 marks)
3)	Define a class Time with hours and minutes as two data members, add necessary member functions to initialize and display data of class. Do not use constructors in a class. Define a member function sum() which adds two Time objects. Invoke the statements like T3.sum(T1, T2) in main (). (07 marks) OR Define a class complex with real and imaginary as two data member, add necessary constructors and member function to initialize and display data of class. Class should overload the + operator to add two complex objects and return the results. Invoke the statements like C3=C1+C2 in main ().(07 marks)
4)	Define Friend Function. Create two classes DM and DB which store the value of distances. DM stores distances in meters and centimeters and DB in feet and inches. Write a program that can read values for the class objects and add one object of DM with another object of DB. Use a friend function to carry out the addition operation. The object stores the results may a DM object or DB object, depending on the units in which the results are required. The display should be in the format of feet and inches or meters and centimeters depending on the object on display. 1 Feet = 0.3048Meter 1Meter = 3.28 Feet 1 Inch = 2.54 Centimeter 1 Centimeter = 0.3937 Inch (07 marks) OR Explain Friend function and its characteristics. 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. (07 makrs)
5)	What is a constructor? Which are the special characteristics of constructor functions? What is the need of “do-nothing” implicit constructor? When the destructor function invoked? (07 marks)
6)	What is Constructor? Write the characteristics of constructor function. Define Class named point which represents 2-D Point, i.e P(x, y). Define Default constructor to initialize both data member value 5, Parameterized constructor to initialize member according to value supplied by user and Copy Constructor. Define Necessary Function and Write a program to test class Point. (07 marks)
7)	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 +. (07 marks)
8)	What is Type conversion? Explain Basic to class type conversion with example. (04 marks) OR Explain the type conversion from basic type to class type and from class type to basic type with proper example. (07 marks)
