Q.1. Discuss the different basic features of Object-Oriented Programming (OOP) in detail, with examples. Explain in detail about basic structures of C++. (5+5 = 10 Marks)

Ans 1.

Basic Features of Object-Oriented Programming

The Object-Oriented programming paradigm is a software approach that describes real-world entities as objects containing data as well as behaviour. Its core features form the base of modern software design.

Encapsulation combines data as well as the functions that work on the data into a single piece that is called a “class” and blocks access directly to internal data through access specifiers such as privacy and open. As an example

Q.2. a) Compare and contrast for loop and while loops detail of execution flow and behaviour. b) Differentiate between the conditional statement and unconditional statements with examples. (5+5 = 10 Marks)

Ans 2.

1. a) For Loop vs While Loop

While and for loops run the same code as long as a conditions is fulfilled, but they differ in terms of structure and their best uses.

The for loop blends conditions, initialization and update into a single header line. It’s most effective when the number

Q.3. Define Arrays. Explain the concept of arrays in C++ programming. How are arrays declared and initialized? Give Examples. (2+3+5 = 10 Marks)

Ans 3.

Definition of Array

An array is made up of elements of the same data type that are kept in contiguous storage locations with a common variable name. Every element can be accessed by an index beginning from zero. Arrays enable multiple similar values to be stored, and processed efficiently without declaring separate

Q.4. Define Friend Function. Compare between Friend function and inline function with give examples. Explain in detail about Operator overloading with examples. (2+3+5 = 10 Marks)

Ans 4.

Friend Function

A friend function that is used in C++ is a member function that does not have access to the private and protected members of the class. It is defined within the class by using the friend keyword, however it is implemented out of the class using the scope resolution operators. It does not belong to the class, however, it is granted special access rights granted by the class.

Friend Function vs Inline

 

Q.5. Recall stream. Draw and explain the stream class hierarchy in C++. (2+3+5 = 10 Marks)

Ans 5.

Definition of Stream

A stream in C++ is an abstraction that indicates a flow of data into or out of a programmer. It serves as an intermediary between the program and output or input devices, such as keyboards or monitor, as well as files. Streams obscure the particulars of how data is physically read or written, and offer an

 

Q.6. Define exception. Explain in detail about exception handling mechanism. (5+5 = 10 Marks)

Ans 6.

Definition of Exception

A problem in C++ is an unexpected or abnormal event that occurs during the execution of a program, and interrupts the normal process. The reason for exceptions is as diverse that of division with zero, error in access to memory, files not identified, or a wrong user input. If handled incorrectly an error causes the program’s termination abruptly and display a message of error. C++ provides a systematic mechanism to recognize and deal with exceptions efficiently and without
