overriding with example.
[4]
Q5) a) What is constructor? What are the characteristics of constructor? Give one
example of constructor.
[6]
b) Write a program to define tow classes alpha and beta containing an integer each
as data members. Define a function sum( ) that will be a friend to both alpha and
beta which will take one object from each class as argument and return the sum
of the data members of the argument objects.
[6]
OR

the results by overloading the operator <<.

[8]
b) List the operator overloading rules. [4]
OR

another class type with example.
[6]

instruction a= (b,c) the larger object of b and c is assigned to a.
[6]
Q9) a) What is the difference between late binding and early binding? [6]
b) What is inheritance? Explain multilevel inheritance with example. [6]
OR
Q10) a) What are the types of inheritance? Explain multiple inheritance with example. [6]
b) Explain mechanism of passing parameters to the base class constructor in
Multilevel inheritance with example.
[6]
Q11) a) What is the difference between opening a file with a constructor function and
opening a file with open () function? When is one method preferred over the
other?
[6]
b) Explain managing console formatted I/O with example. [5]
