Time: 3 Hours Max. Marks: 100

NOTE:

· Question 1 is compulsory and carries 28 marks. Answer any FOUR questions from the rest. Marks are indicated against each question.

· Parts of a question should be answered at the same place.

Q.1 a. Compare the concepts of structures in ‘C’ & classes in ‘C++’ with the help of suitable examples.

b. Differentiate between static polymorphism and run-time polymorphism.

c. Compare ‘inline function’ in C++ with macros of C language.

d. Can constructors and destructors be overloaded? Comment.

e. State why Operator Overloading is required. Mention the operators in C++ that cannot be overloaded?

f. Discuss the uses of friend function in C++.

g. Give the general syntax of function templates and explain their use. (74)

Q.2 a. Discuss and compare procedure oriented programming with object oriented programming.

b. Write a C++ code to demonstrate the concept of using array of objects to create an array of ten employees (reading their entire personal data: Name, age, emp_ID, sex, address) and print the same. (9+9)

Q.3 a. Explain Multiple Inheritance, Multilevel inheritance, Hierarchical Inheritance & Hybrid Inheritance illustratively and with the help of C++ code.

b. Explain parameterised constructors with the help of suitable examples. (12+6)

Q.4 a. Compare and contrast the following with suitable examples:

(i) cin and cout in C++.

(ii) copy constructor and assignment operator.

b. Write a C++ program to read two strings S1 and S2 and perform the task S3 = S1 + S2 and print the string S3. Consider overloading of the ‘+’ operator using friend functions in C++. (8+10)

Q.5 a. Explain the behaviour of constructors in Multiple Inheritance.

b. Write a function NewStrCmp that does the same job as strcmp without using string library function (use pointers)

c. Differentiate between a virtual function and a pure virtual function. Discuss the role of pure virtual function. (6+6+6)

Q.6 a. Differentiate between Abstraction and Encapsulation with the help of example.

b. Explain with the help of an example virtual base class. What is its role in C++?

c. How does overloading a suffix and prefix document operator differ. Explain it with the help of an example. (6+6+6)

Q.7 Write short notes on (Any THREE)

(i) Exception Handling.

(ii) Template class.

(iii) File handling.

(iv) Friend class. (6+6+6)
