Coding Hub

Learning to code is less about memorising syntax and more about practice: write a little, run it, see what breaks and fix it. Coding Hub is built around that loop, with lessons, a code runner and an AI tutor for more than ninety programming subjects.

Lessons for Every Language

Learn C, C++, Java, Python, JavaScript, Go and many more step by step. Each lesson has clear theory, highlighted code and a quick check at the end.

Data Structures and Algorithms

Arrays, linked lists, trees, graphs, hashing, recursion and dynamic programming are taught with Big-O analysis. Animated visualizers show sorting, searching and graph algorithms step by step.

Write and Run Code

The built-in code runner supports ten languages, so you can test an idea without installing anything.

Algo Lab and Interview Questions

Coding problems with solutions are grouped by interview patterns, and interview questions come with hints, model answers and example code.

26,000+ Quiz Questions and Mock Tests

Quizzes move from easy to hard with an explanation for every answer. Mock tests mix multiple choice, theory and code, and wrong answers come back for spaced review.

An AI Tutor Beside You

Ask about any lesson, share a photo of your code or practise a mock interview. A seven-day AI study plan balances concepts, coding and interview prep.

Stay on Track

Streaks, XP, badges and leaderboards keep you going, with a glossary, flashcards and a tech news feed for quick reading.

Begin with one language on Coding Hub, write code every day, and the rest will follow.
