Quick Start

Using Makefile (Recommended)

make                   # Build console version (default)
make console           # Build console version only
make gui               # Build GUI version only (Windows)
make clean             # Clean all build artifacts
make run               # Build and run console version

Using Build Scripts

Windows (Batch Files)

build_console.bat      # Build console version
build_gui.bat          # Build GUI version

Unix/Linux/macOS (Shell Scripts)

./build_console.sh     # Build console version

Running the Applications

build/cinema_system.exe     # Console version (Windows)
build/cinema_system         # Console version (Unix/Linux/macOS)
build/cinema_gui.exe        # GUI version (Windows only)

How It Works

1. Authentication: Login as admin or client with provided credentials
2. Movie Management: Admin adds movies → Automatic room assignment (1-19)
3. Booking Process: Client selects movie → Chooses date → Selects seats → Payment
4. Payment: Credit card validation using Luhn algorithm
5. Confirmation: Unique ticket ID generated with booking details

Requirements

• C Compiler (GCC/MinGW recommended)
• Make (optional, for using Makefile)
• Windows OS (for GUI version)
• Unix-like OS support (console version)
• Minimum 4MB RAM for operation

Usage

Admin: Login with admin / admin to manage movies and view system analytics
