<strong>FINAL TERM EXAMINATION 2011
1-define composition and give its example with coding
Answer:- (Page 53)
An object may be composed of other smaller objects, the relationship between the “part” objects and the “whole” object is known as Composition.
Example: Ali is made up of different body parts; They can’t exist independent of Ali.
2-what are container classes? How many types of container classes are there?
Answer:- (Page 312)
Container is an object that contains a collection of data elements like we have studied before now we will study them in detail. STL provides three kinds of containers,
1. Sequence Containers
2. Associative Containers
3. Container Adapters
3-what is virtual inheritance?
Answer:- (Page 253)
In virtual inheritance there is exactly one copy of the anonymous base class object
4-can a constructor throw exception? If it fails, how should this error be handled?
Answer:
One-stage constructors should throw if they fail to fully initialize the object. If the object cannot be initialized, it must not be allowed to exist, so the constructor must throw.
5-define inheritance and give its example.
Answer:- (Page 29)
Derived class inherits all the characteristics of the base class
Besides inherited characteristics, derived class may have its own unique characteristics
Major benefit of inheritance is reuse
7-what is constructor?
Answer:- (Page 74)
Constructor is used to initialize the objects of a class. Constructor is used to ensure that object is in well defined state at the time of creation.
8-define static and dynamic binding.
Answer:- (Page 227)
Static binding means that target function for a call is selected at compile time. Dynamic binding means that target function for a call is selected at run time.
