Quiz App is a customizable online testing platform allowing users to test their knowledge across different subjects, difficulty levels, and question numbers. Designed for students, professionals, and anyone eager to learn, Quiz App offers a tailored experience for a variety of knowledge fields. Built with HTML, CSS, and JavaScript, the app is structured for easy navigation, engaging design, and immediate feedback on performance.

Project Description:

Quiz App is a user-focused application where participants can select their desired subject, difficulty level, and number of questions for a quiz. Using JavaScript for logic and an API to fetch questions, the app evaluates the user’s responses and provides a final score. The responsive HTML and CSS layout ensures compatibility across devices, making it ideal for both casual and serious test-takers.

Project Details:

1. User Interface

• Design: A clean, intuitive layout where users can easily select topics, levels, and customize question count.
• Styling: CSS is used for a responsive, visually appealing design.

2. Functionality

• Question Fetching: The app fetches questions from an API based on selected criteria.
• Answer Submission: Users can submit answers, which are evaluated to calculate the score.
• Score Display: Upon completion, the app displays the user's score and feedback.
• API Integration: Uses a quiz-based API to retrieve questions dynamically, enhancing the variety and relevance of the quiz content.

3. Object-Oriented Design (OOP)

• Classes:
  • Quiz: Manages question fetching, storing, and the quiz flow.
  • Question: Represents individual questions, stores options and correct answers.
  • User: Manages user selections and tracks scores.
• Encapsulation: Core functionalities (like answer validation) are wrapped within classes for better structure and future scalability.
• Inheritance: Could be extended to support different types of quizzes (e.g., timed quizzes) by inheriting from base classes.

Example Usage:
