This document describes a project to build a secure web-based code editor for C programming language. The objectives are to create an online platform where programmers can write and compile C programs in their web browser without needing to install any software. The proposed system uses cloud computing to provide each user with their own computing environment in a Docker container. This allows programs to be run on the server-side while displaying output in the client's browser. Key features of the code editor include syntax highlighting, auto-completion and code folding. The system aims to allow users to easily write, compile, run and share C programs from any internet-connected device.
