C Coding is a fully responsive React.js-based learning platform designed to help beginners and intermediate learners practice, revise, and master C programming.
Originally started as a simple C programs repository, this project has now evolved into a structured web platform that categorizes 79 C programs into three difficulty levels with clean UI, animations, and smooth navigation.

-
🏠 Home Page
- Welcome screen with intro and animations.
-
🧱 Levels Page
- Displays three level boxes – Beginner, Intermediate, and Advanced.
- Each box lists topics under that level.
-
📄 Level-Wise Code Pages
- Each level box navigates to its its own detailed page.
- Every topic is displayed in a card/box with a "View Code" button.
- Clicking the button opens the respective program/code page.
-
💻 Program Page
- Displays the selected program with proper formatting.
- Code is rendered using Prism React Syntax Highlighter for clean syntax highlighting.
- Includes a "Copy Code" button for quick copying.
- Provides a "View Raw on GitHub" button to access the original source file.
✅ Fully responsive UI (desktop + mobile)
✅ Organized C programs by logic complexity
✅ Modern look with AOS (Animate on Scroll) effects

✅ Lifecycle handling using useEffect
✅ Easy-to-use and clean interface for beginners
- Framework: React.js (CRA - Create React App)
- Routing: React Router DOM
- Styling: CSS3
- Animations: AOS (Animate On Scroll)
- Logic: React Hooks (
useEffect) - Icons by React icons

Basic syntax and fundamental logic Examples: arithmetic operations, conditionals, swapping, tables
Moderate logic involving arrays, strings, loops, recursion, and structures
Advanced concepts such as matrices, recursion-heavy problems, quizzes, and number systems
📌 All programs were written during my personal C learning journey.
