How It Works

The program is structured around three independent modules:

1. Learn Module
Displays traffic light meanings and road safety rules. An admin can append custom instructions that appear here at runtime.

2. Admin Panel
Allows a privileged user to add new quiz questions (with up to 3 options each), delete existing ones, view the full question bank, and add extra learning instructions — all without recompiling.

3. Quiz Engine
Fetches questions from the bank, applies a Fisher-Yates partial shuffle to randomise order, presents the chosen number of questions, gives immediate right/wrong feedback, and saves the result to the session history.

Concepts Demonstrated

• Arrays and multi-dimensional arrays
• Functions and modular program design
• Input validation with cin.fail() and stream recovery
• String handling with getline
• Random number generation (rand, srand)
• Loops, switch statements, and menu-driven architecture
