A real code editor — write and run instantly

Syntax highlighting and code execution on a secure, sandboxed runtime.

💬 Python runs entirely in your browser (WebAssembly / Pyodide) — input() prompts for data live. No code or data is ever sent to a server.

ℹ️ Input (stdin) — one value per line: For C++: this compiler runs your code on a remote server (real GCC), so it cannot pause mid-execution. The program will read the values below in order — each line answers one cin call, in the same order as in your code. Type them BEFORE clicking "Run".
