I’m <strong>Guntu Jothi Ganesh</strong>, a 18-year-old self-taught developer with a growing passion for system-level programming and open-source. I recently completed <strong>two versions</strong> of a command-line calculator using <strong>C</strong>, and now I'm building a <strong>GUI version using GTK+ 3</strong> on Windows.</p> <p>This post is a quick showcase of my progress, what I’ve learned, and what I’m working toward.</p> <h2> 🛠️ What I Built </h2> <h3> 🔹 Version 1: Basic Calculator </h3> <ul> <li>Operates with <code>+</code>, <code>-</code>, <code>*</code>, <code>/</code> </li> <li>Takes two inputs and an operator</li> <li>Displays a result with simple output</li> </ul> <h3> 🔹 Version 2: Improved CLI Calculator </h3> <ul> <li>🔁 Added a loop for continuous calculations</li> <li>❌ Checks for divide-by-zero</li> <li>🎯 Cleaner input/output formatting</li> <li>🧹 Graceful exit</li> </ul> <p>📂 GitHub: <a href="https://github.com/logicCrafter320/calculator_v2.c" rel="noopener noreferrer">calculator_v2.c</a></p> <h2> 🧩 Now Building: <strong>Version 3 - GUI Calculator with GTK</strong> </h2> <p>I’m currently working on a <strong>graphical calculator using GTK+</strong> — built in C with a nice interface, buttons for input, and result display in a GUI window.</p> <h3> GTK Features in Progress: </h3> <ul> <li>🖱️ Buttons for digits and operations</li> <li>🪟 GTK window with layout design</li> <li>🧠 Future plan: scientific operations (log, sin, cos, etc.)</li> <li>💡 Learning how to use GTK in <strong>MSYS2 on Windows</strong> </li> </ul> <p>📂 GitHub (work-in-progress): <a href="https://github.com/logicCrafter320/gtk_calculator_v3" rel="noopener noreferrer">gtk_calculator_v3</a></p> <h2> 🔍 What I’ve Learned So Far </h2> <ul> <li>Using <code>switch-case</code>, input handling, and loops in C</li> <li>How to avoid <code>scanf</code> pitfalls</li> <li>Writing readable, maintainable C code</li> <li>Compiling GTK projects with <code>gcc</code> and <code>pkg-config</code> </li> <li>Publishing releases and managing GitHub repos</li> </ul> <h2> 🎯 What’s Next? </h2> <ul> <li>Polish the GTK interface and layout</li> <li>Add scientific calculator functions</li> <li>Package it cleanly with README, screenshots, and instructions</li> <li>Start contributing to beginner open-source C projects</li> </ul> <h2> 📣 I'd Love Your Feedback! </h2> <p>If you’re a C dev, GTK user, or just exploring programming, I’d love to hear your thoughts and suggestions.
