Coding Hub: Learn to Code

Master programming from your phone. Coding Hub takes you from your first line of code to interview-ready — six core languages plus Data Structures & Algorithms through structured lessons, hands-on practice and a personal AI tutor.

📚 LESSONS THAT MAKE SENSE

Learn C, C++, Java, Python, JavaScript and Go step by step with topic-by-topic curriculum progression. Every subtopic gives you clear theory, guided practice and a quick summary, with syntax-highlighted, runnable code and plain-English explanations. Browse by Subject, Topic and Subtopic, with difficulty tags, search and bookmarks.

🧠 DATA STRUCTURES & ALGORITHMS

Build real problem-solving skills: arrays, linked lists, stacks, queues, trees, graphs, hashing, sorting, recursion, dynamic programming and Big-O analysis — the coding interview patterns top tech companies test.

💻 CODE EDITOR & ONLINE COMPILER

Write and run code instantly — no IDE, no setup. The built-in runner supports Python, Java, Go, C++, C, JavaScript, TypeScript, Rust, Dart, Kotlin and Swift. Solve coding problems with hidden test cases and reference solutions while the AI checks your output.

🤖 SMART MENTOR AI TUTOR

Stuck on a concept? Ask anything and get lesson-aware, developer-focused answers. Try mock-interview mode, or snap a photo of code or a diagram to ask about it. Get an AI-built 7-day study plan covering concept review, coding practice and interview prep.

✅ QUIZZES & MOCK TESTS

Practice quizzes scale from Easy to Medium to Hard with instant feedback, and every answer comes with an explanation so you understand why, not just what. Timed mock tests mix multiple-choice, theory and coding questions with progressive difficulty levels, result analytics, per-question breakdowns and improvement tips. Review your quiz history, re-attempt anything, or build custom topic tests around exactly the skills your next interview will cover.

📊 PROGRESS & WEAK TOPIC ANALYSIS

Track scores over time, study minutes, completed topics and your lowest-accuracy weak topics on a subject-wise progress dashboard. Keep streaks alive with daily goals, a daily check-in quiz and an AI revision card. Climb global and per-subject leaderboards.

🌐 BUILT FOR EVERYONE

Works offline, with light and dark themes and an interface in English, Hindi, Kannada, Tamil and Telugu that protects code and technical terms during translation. Catch up on a Today's Updates tech news feed.
