C++ Online Compiler is a lightweight, web-based Integrated Development Environment (IDE) built entirely in Python using Streamlit. It allows users to write, compile, and execute C++ code in a secure, sandboxed environment directly from their browser, complete with custom CSS styling to mimic professional IDEs.
| User Type | Core Use Case |
|---|---|
| Students | Quickly testing algorithms and assignments without local setup. |
| Instructors | Demonstrating C++ concepts in live environments. |
| Developers | Scratchpad for testing C++17 features on the go. |
❌ Before C++ Online IDE:
- Cumbersome local setup required for g++ and MinGW.
- Difficulty sharing code snippets that compile reliably.
- Heavy IDEs taking up gigabytes of disk space.
✅ After C++ Online IDE:
+ Zero-configuration cloud compilation.
+ Instant execution with standard input/output support.
+ Lightweight, beautifully styled interface accessible anywhere.Purpose: To lower the barrier to entry for systems programming by providing an accessible, instant C++ environment.
| Principle | Application |
|---|---|
| Simplicity | A single app.py architecture that is easy to deploy and scale. |
| Security First | utilizing tempfile and subprocess sandboxing to prevent host compromise. |
| Aesthetic UX | Custom CSS overriding default Streamlit styles for a true "Dark Mode" IDE feel. |
| Feature | Status | Description |
|---|---|---|
| Multi-File Support | 🟢 Live | Manage and compile multiple .cpp and .h files simultaneously. |
| Sandboxed Execution | 🟢 Live | Safe code execution with timeout limits to prevent infinite loops. |
| Custom Input | 🟢 Live | Provide stdin directly via the UI for algorithmic testing. |
| Real-time Compilation Logs | 🟢 Live | Detailed g++ output and error tracing. |

Ensure Dependencies are Installed: You must have
g++installed and accessible in your system's PATH. -
Clone the repository:
git clone https://github.com/prithishmisra23/cpp-online-compiler.git cd cpp-online-compiler -
Install Python dependencies:
pip install -r requirements.txt
-
Run the IDE:
streamlit run app.py
| Component | Status | Recommendation |
|---|---|---|
| Execution Sandbox | 🔒 Secured | Uses tempfile.TemporaryDirectory for isolated compilation. |
| Timeout Limits | 🔒 Secured | Subprocess timeouts prevent infinite loop DOS attacks. |
| System Calls | C++ code can technically make system calls. Consider Docker for production. |
