Exploring C++ and Object Oriented Concepts

What is the primary difference between C and C++?

• C uses classes; C++ does not support classes.

• C is a high-level language; C++ is low-level.

• C is procedural; C++ supports object-oriented programming.

• C is used for system programming; C++ is only for web development.

List one disadvantage of conventional programming.

• Increased development time due to manual coding.

• Lower initial costs due to automated tools.

• Faster execution time compared to other programming methods.

• Reduced flexibility in adapting to new requirements.

How has C++ evolved from its predecessor C?

• C++ introduced object-oriented programming, stronger type checking, function overloading, templates, and standard libraries.

• C++ does not support any form of type checking.

• C++ is a purely functional programming language.

• C++ removed all procedural programming features from C.

What are the key concepts of Object Oriented Programming?

• Syntax, Semantics, Compilation, Execution

• Data Structures, Algorithms, Functions, Variables

• Encapsulation, Abstraction, Inheritance, Polymorphism

• Composition, Aggregation, Delegation, Interface

Describe the basic structure of a C++ program.

• A basic C++ program consists of only comments and whitespace.

• A basic C++ program requires a graphical user interface.

• A basic C++ program is written entirely in Python.

• A basic C++ program includes preprocessor directives, a main function, statements, and a return statement.

What is one advantage of using Object Oriented Programming?

• Code reusability through inheritance.

• Reduced performance due to abstraction.

• Increased complexity in code management.

• Limited access to data and methods.

Explain the purpose of the scope resolution operator in C++.

• To define new data types in C++.

• To create loops in C++ programs.

• The scope resolution operator in C++ is used to access global variables, class members, and to resolve naming conflicts.

• To manage memory allocation in C++.

What is a namespace in C++ and why is it used?

• A namespace is a way to declare global variables.

• Namespaces are used to define classes in C++.

• A namespace in C++ is used to organize code and prevent name conflicts.

• A namespace in C++ is a type of variable.

How do you create a class in C++?

• class ClassName { public: int memberVariable; void memberFunction(); };

• class ClassName { private: int memberVariable; };

• class ClassName { public: void memberFunction() { int memberVariable; }; };

• class ClassName { int memberVariable; void memberFunction() {} };

What is encapsulation in the context of OOP?

• Encapsulation is the process of creating multiple instances of a class.

• Encapsulation is the method of exposing all data and methods of an object to the outside world.

• Encapsulation is the bundling of data and methods that operate on that data, restricting direct access to some of the object's components.

• Encapsulation refers to the inheritance of properties from a parent class.
