GTK Bank System

🚀 A Modern Banking Solution with GTK, C, and PDF Receipt Generation

Welcome to the GTK Bank System – a robust desktop banking application designed with secure transactions, PDF receipt generation, and an intuitive UI. Built using C, GTK, and Cairo, this project showcases how traditional banking systems can be modernized with elegant graphical interfaces.

🌟 Why I Built This

I developed this project to demonstrate that C is not limited to low-level programming. By integrating GTK for UI and Cairo for PDF generation, I have built a full-fledged banking system featuring:

• Secure file-based user authentication
• Real-time transaction tracking
• Automatic PDF receipt generation
• Cross-platform compatibility

This project reflects my expertise in GUI development, data persistence, and system design using pure C.

🌟 Installation

Prerequisites

For Linux:

Ensure you have GTK installed on your system:

sudo apt update && sudo apt install libgtk-3-dev

For Windows:

1. Install GTK
   • Download and install MSYS2 from https://www.msys2.org/.
   • Open MSYS2 MinGW 64-bit and run the following commands to install GTK:

   pacman -S mingw-w64-x86_64-gtk3
   pacman -S mingw-w64-x86_64-gcc

2. Add GTK to Path
   • Find your MSYS2 installation directory (e.g., C:\msys64\mingw64\bin) and add it to your system Environment Variables under Path.

Clone the Repository

cd GTK-Bank-System

Compile and Run

On Linux:

gcc Bank_System.c -o Bank_System `pkg-config --cflags --libs gtk+-3.0`
./Bank_System

On Windows:

gcc Bank_System.c -o Bank_System.exe `pkg-config --cflags --libs gtk+-3.0`
./Bank_System.exe

🛠 Usage

1. Run the program and enter your username and password.
2. If new, a new account will be created for you.
3. After login, you can deposit, withdraw, change password, or view transaction history.
4. Click Logout to switch users securely.
5. The receipt button lets you view past transactions.

🎨 UI & Aesthetics

I've designed the interface to be clean, minimalistic, and easy to use. The application is centered on the screen for a modern feel, and fonts are optimized for clarity.

Enhancing UI/UX in C? YES, IT'S POSSIBLE!

Icons, colors, and spacing are carefully arranged to improve usability while keeping performance optimal.
