Time : 3 Hours Answer A L L Questions Max. Marks 100
PART-A
(10 x 2 = 20 Marks)
1. Give 4 expressions to access array
elements.
2. Declare a pointer to a function
which accepts one integer argument and returns an integer.
3. What is function prototype?
4. Differentiate class and structure.
5. Can a static member function access
non static member variables? Justify.
6. How are data members initialized in
C++?
7. What is an iterator?
8. Write 4 functions for manipulating
file pointers. What is their use?
9. What is a generic function?
10. What is namespace ?
Part-B
(5* 16 = 80 Marks)
11. a. Write a C program to swap 2
integers using function swap which takes the 2 integers as parameters. Print
the swapped result in main. (8)
b. A file contains letters, digits and
special characters. Write a C program to count the number of characters in the
file. (8)
12. a.l. Explain the use of default
arguments with suitable examples.
12.a.2. A class math has 2 integer
members a and b; Initialise and display the data members. A friend function sum
finds the sum of a and b and prints the result. Write the complete program to print
the sum of the 2 members using sum.
(OR)
12.b.l. A class X has an integer
member a; A class Y has an integer member b; Initialise and display the data
members. A friend function sum finds the sum of a and b and prints the result.
Write the complete program.
12.b.2. Explain function over loading
with examples.
13.a.l. Write a program to count the
number of objects created. (5)
13.a.2. Class employee has name and
age as data members. Print() is a pure virtual function. Class manager is
inherited from employee. Manager is represented by his name, age and salary
which is double. Class supervisor is inherited from employee. Supervisor is
represented by his name, age and dept_name which is string. Write a program to
implement the hierarchy and display the particulars of manager and supervisor
objects. (11)
(OR)
13. b. Explain any 4 forms of
inheritance giving an example for each.
14.a.l. Explain the following giving
an example for each : (11)
(i) multiple handlers (ii)restricting
exceptions (iii) rethrowing an exception
14.a.2. Write a program to divide a/b.
Raise an exception if b is 0. (5)
(OR)
14.b.l. A class contains 2 generic
members. Use constructor and show displays the data members. Write a program to
display an object with float and int members and another
object with int and char members. (8)
14.b.2. Write a generic function to
swap the 2 parameters of any data type and display the swapped value in the
function itself. Call the generic function from main to swap 2 integer values
and 2 char values. (8)
15.a.1. Write a program to access a
vector through iterator. Assign elements to the vector, display the vector and
modify the contents of vector.
15.a.2. Write a C++ program to create
class string with name and int length. Dynamically allocate memory
for the data members; method disp() prints the name ; method join() takes 2
string objects as arguments and concatenates the name data member.
(OR)
15.b.l. Write a C++ program to create
a file ITEM and write name and cost fields into the file. Then read the file
and display the details.
15.b.2. Explain any 3 ios format
functions with an example for each.
