Free CPP Programming Languages & Frameworks Questions and Answers

Question 1

Which of the following is an object-oriented programming language?

Accepted Answer

Python

Answer

Python is an object-oriented programming (OOP) language because it supports core OOP concepts such as classes, objects, inheritance, polymorphism, and encapsulation. Developers can define custom data types and their behaviors, making code modular and reusable. In contrast, C, Assembly, and Fortran are primarily procedural or low-level languages without native OOP paradigms.

Question 2

What is the purpose of a compiler in programming?

Accepted Answer

To convert source code into machine code

Answer

The primary purpose of a compiler is to translate human-readable source code, written in a high-level programming language, into machine code. This machine code is a low-level language directly executable by the computer's central processing unit (CPU). This conversion is essential for creating standalone executable programs.

Question 3

Which of the following is a framework used for building mobile applications?

Accepted Answer

Flutter

Answer

Flutter is an open-source UI software development kit created by Google, specifically designed for building natively compiled applications for mobile, web, and desktop from a single codebase. It provides a complete framework for developing cross-platform mobile applications. Django, Ruby on Rails, and Spring Boot are frameworks primarily used for web backend development.

Question 4

What is the difference between a framework and a library?

Accepted Answer

A framework calls the code written by the developer, while a library is called by the developer

Answer

The key difference lies in the 'Inversion of Control' principle: a framework dictates the application's flow and calls the developer's code at specific points. Conversely, a library is a collection of functions or modules that the developer explicitly calls and integrates into their application as needed. Frameworks provide a complete structure, while libraries offer specific functionalities.

Question 5

Which programming language is primarily used for web development?

Accepted Answer

JavaScript

Answer

JavaScript is the foundational and most widely used programming language for web development, particularly for client-side scripting. It enables interactive and dynamic content on web pages that run directly in web browsers. With Node.js, JavaScript can also be used for server-side development, making it a full-stack web language.
