Learn how to defend the code.</strong></p> <p>LabCode Fixer &amp; Viva Coach is an AI-powered debugging and viva preparation tool built for me and a fellow college student who work with programming assignments and laboratory exercises.</p> <p>While debugging a program, fixing the error is only one part of the problem. During a laboratory viva, a student may also be asked:</p> <ul> <li>Why did this error occur?</li> <li>Which line caused the error?</li> <li>What exactly went wrong?</li> <li>Why was this particular fix used?</li> <li>What programming concept is involved?</li> <li>What would happen if the input changed?</li> </ul> <p>I wanted to build something that helps with more than just getting code to run.</p> <p>The idea is simple:</p> <p><strong>Debug → Understand → Correct → Defend</strong></p> <p>The student provides:</p> <ol> <li>Programming language</li> <li>Broken code</li> <li>Compiler or runtime error</li> </ol> <p>The application then provides:</p> <ol> <li> <strong>Why It Broke</strong> — an explanation of the actual error and the programming concept involved.</li> <li> <strong>Corrected Code</strong> — a corrected version while preserving the original purpose and structure wherever possible.</li> <li> <strong>3 Viva Questions</strong> — technical questions generated specifically from the student's code and error.</li> </ol> <p>The current version supports:</p> <ul> <li>Java</li> <li>Python</li> <li>C</li> <li>C++</li> </ul> <p>The goal is not just to help students fix errors, but to help them understand the fix and prepare to explain their code during a viva.</p> <h2> Demo </h2> <p>The demo shows the complete workflow:</p> <p><strong>Enter code → Enter error → Analyze → Understand the error → See corrected code → Practice viva questions</strong></p> <p><strong>Demo video:</strong><br><br> </p> <div class="crayons-card c-embed text-styles text-styles--secondary"> <div class="c-embed__content"> <div class="c-embed__body flex items-center justify-between"> <a href="https://screenapp.io/app/share/wNz51KRtxbt9nvpbb_WIlAUz" rel="noopener noreferrer" class="c-link fw-bold flex items-center"> <span class="mr-2">screenapp.io</span> </a> </div> </div> </div> <p>The demo is approximately 1 minute and 31 seconds long and focuses on the working application.</p> <h2> Code </h2> <p>The complete source code is available on GitHub:</p> <div class="ltag-github-readme-tag"> <div class="readme-overview"> <h2> <img src="https://assets.dev.to/assets/github-logo-5a155e1f9a670af7944dd5e12375bc76ed542ea80224905ecaf878b9157cdefc.svg" alt="GitHub logo"> <a href="https://github.com/Namratha600" rel="noopener noreferrer"> Namratha600 </a> / <a href="https://github.com/Namratha600/labcode-viva-coach." rel="noopener noreferrer"> labcode-viva-coach. </a> </h2> <h3> AI-powered debugging and viva preparation tool that explains programming errors, provides corrected code, and generates code-specific viva questions. </h3> </div> <div class="ltag-github-body"> <div id="readme" class="md"><div class="markdown-heading"> <h1 class="heading-element">LabCode Fixer &amp; Viva Coach</h1> </div> <blockquote> <p><strong>Don't just fix the bug.

The application explains why the code failed, provides a corrected version, and generates three technical viva questions based on the student's actual code.</p> <div class="markdown-heading"> <h2 class="heading-element">Problem</h2> </div> <p>Students often use AI tools to fix compiler or runtime errors, but they may still struggle to explain the solution during a laboratory viva.</p> <p>A professor may ask:</p> <ul> <li>Why did this error occur?</li> <li>Which line caused the error?</li> <li>What value caused the problem?</li> <li>Why did you use this particular fix?</li> <li>What happens if the input changes?</li> <li>What programming concept is involved?</li> </ul> <p>LabCode Fixer &amp; Viva Coach is designed to help students understand their errors and prepare for these questions.</p> <div class="markdown-heading"> <h2 class="heading-element">How It Works</h2> </div> <p>The application…</p></div> </div> <div class="gh-btn-container"><a class="gh-btn" href="https://github.com/Namratha600/labcode-viva-coach." rel="noopener noreferrer">View on GitHub</a></div> </div> <p>The repository contains:</p> <ul> <li><code>backend/main.py</code></li> <li><code>backend/requirements.txt</code></li> <li><code>frontend/app.py</code></li> <li><code>README.md</code></li> <li><code>LICENSE</code></li> <li><code>.gitignore</code></li> </ul> <p>The Python virtual environment and downloaded AI model files are not included in the repository.</p> <h2> How I Built It </h2> <p>The project uses a simple architecture where each component has a clear responsibility.</p> <div class="highlight js-code-highlight"> <pre class="highlight plaintext"><code> text Student | v Streamlit Frontend | v FastAPI Backend | v Ollama | v Gemma 2B | v AI Analysis | v Streamlit Frontend </code></pre> </div> devchallenge weekendchallenge hf26challenge
