CS 237-OBJECT ORIENTED PROGRAMMING
PART A
1.Why is OOP methodology considered to be the better approach for real life problems?
2.What are the use of pointers in C++?
3.How do objects interact?
4.What is the differences between a constructor and destructor?
5.Give atleast two examples of compile time polymorphism.
6.Why is the derived class constructor called before the base class
Constructor?
7.Give the syntax of declaring a function template.
8.What are input and ouput streams?
9.What are the three kinds of class members?
10.What is meant by member access modifiers?
PART B
11 (i) Write a program that generates a template class by which one can perform integer type data addition and float type data addition also.
(ii) How are unusaul error conditions avoider using C++?
12(a) What are the elements of object oriented programming? Discuss them in detail.
(b) What are the various data types allowed in C++? Give one example for each type.
13 (a) (i) Using the concept of function overloading,write a program in C++ to find the maximum of three integers and three float numbers
(ii) Which are the C++ operators which cannot be overloaded.
14.(a) (i) Write a program which initialised 10 and 200 to member data and then calculate the sum of these.
(ii) Write a program which reads a complex number copy that into another. Use copy constructor for writing program.
(b) (i) What is the function of this pointers?
(ii) What do you understand by static member and static function? How to declare them?
15.(a) (i) Specify the accesss modifiers of the class members.
(ii) Give the general form of an interface and how is it implemented.
(b) (i) Give two parts of method declaration. How is a static method invoked? When will the method complete execution and return to the caller? How will methods return more than one result?
(ii) Write a program to compute the volume of a box.
