A desktop quiz application built in C++ using Raylib with PostgreSQL (Supabase) integration for storing quiz results.
The project was developed as a learning experience in GUI programming, state management, database connectivity, and game/application development using C++.
Screenshots of the quiz interface, gameplay, and result screens.
- Interactive graphical interface using Raylib
- 30 multiple-choice questions
- Randomized question order
- Timer-based scoring system
- Dynamic score calculation
- Pause & Resume functionality
- Credits screen
- PRN (Student ID) input
- Result screen displaying score and completion time
- PostgreSQL (Supabase) database integration
- Automatic result storage
The application rewards quick and accurate answers.
- Correct answers earn points based on response time.
- Faster responses receive higher scores.
- Incorrect answers reduce the score.
