About this app

Compiler design visulizer– Visual Compiler Lab transforms how you learn compiler design. Instead of reading dull theory, you see compilation happen live. Type any arithmetic or logical expression, and CodeFlow guides you through the entire compiler pipeline: source code → colourful tokens → interactive parse tree → three‑address code → optimized output. The lexical analyzer highlights every keyword, identifier, operator and constant. The parse tree visualizer lets you pan, zoom and tap on any node to understand syntax instantly. The three‑address code generator shows each step with temporary variables, and the optimizer performs constant folding right before your eyes. Whether you are preparing for GATE, university exams, or a technical interview, CodeFlow covers 24+ compiler topics – from lexical analysis, parsing (LL, LR, LALR), semantic analysis and symbol tables to intermediate representations, SSA, code optimization, register allocation, runtime environments, JIT compilation and LLVM. Practice with 150+ GATE PYQs, filter by year and topic, and solve step‑by‑step with a built‑in timer. The smart practice module includes MCQs, output‑based questions, and a unique step execution mode that walks you through tokenization, parsing and evaluation one step at a time. Everything works 100% offline – no internet, no backend. The dark, VS‑Code‑inspired interface is easy on the eyes, and the app tracks your progress, weak topics and XP scores using local storage. Perfect for students, teachers and self‑learners who want to see before they compile. Download CodeFlow now and watch code transform.
