FULL MARKS-70
TIME:3 HOURS
ans ques. No.1 which is compulsory and any 5 from the rest.
The figures in the right-hand margin indicate marks.
1.Answer the subsequent questions: [2*10]
(a) What is an iterator in C++?
(b) For the statement:
A ob;
ob1=20;
which mechanism should be carried out for successful execution of the above statements?
(c) What is the work of set_terminate() function?
(d) For the subsequent function definition:
void abc(int a,int b=10,int c=20)
{
cout<
what will be the output of the subsequent function calls:
abc(5,6);
abc(50);
(e) What is the work of catch(...)?
(f) What is a pure virtual function?Why is it used?
(g) For the subsequent declaration:
#define sqr(x) {return x*x;}
what will be the outcome of the function call:
sqr(4+4)?
(h) What is the difference ranging from a template class and a class template?
(i) define call by reference.
(j) describe an inline function.
2. What is inheritance?Describe the different kinds of inheritances with examples for every one. [10]
3. what is function overriding?How can we eliminate function overriding,describe with suitable example. [10]
4. Consider a multilevel inheritance with classes A,B,C and D.
Here A is the topmost parent class,B is its child,C is the child of B,D is the child of C.
A is an abstract class containing member function get() to learn any value,which is implemented in B and C for studying value i.e. get() in B reads value x as member and get() in C reads value y as member,class D contains a member function add() to add x and y.
Write a C++ program for the above. [10]
5. What is an exception,describe the mechanisms of exception handling with suitable examples? [10]
6. What is a constructor;explain its kinds with suitable examples from every. [10]
7. Create a class complex with real and imaginary parts as member variables,member functions get() and disp() to input & display the complex number respectively.Write a program using the above class to overload + and - operators for performing addition and subtraction of 2 complex numbers. [10]
8. Create 2 classes Meter and Centimeter to represent meters and centimeters respectively.Use improper conversion routines to convert
(a)Meters to Centimeters and
(b)Centimeters to meters. [5+5]
