When I first learned C++, I spent more time installing MinGW and configuring VS Code than writing code, just to run bits/stdc++.h. Every time I changed machines, whether it was the lab computer or during an exam, I had to start all over again, and many classmates were stuck at the same step. Dev-C++ was easy to run after installation, but its interface was old and hardly customizable.

Sameko Dev C++ was created to provide both: you can start coding right after installation, while still being modern and customizable to your liking.

⚡ Install and code, compile quickly

- GCC 16 is included on Windows, no need to install MinGW or configure anything extra.

- bits/stdc++.h is pre-compiled (PCH), a normal build takes about 500-700 ms. Unmodified files can run immediately, without recompiling.

- Supports C++11 to C++26, with optional flags (e.g., -DLOCAL).

- There’s an installation version (self-updating) and a portable version that runs directly after extraction, suitable for school computers.

🏆 Made for Competitive Programming

- Input / Output / Expected box, automatically grades AC / WA / TLE.

- Integrated Competitive Companion: with one click, you can retrieve problems and tests from Codeforces, AtCoder...

- Run all tests in parallel or one test at a time, read large input directly from .txt files.

- Outputs show each line immediately as the program runs; even infinite printing will not freeze the app.

🐞 Easy-to-use GDB Debugger

- Click the left margin to set breakpoints, with conditional breakpoints available.

- View vector, map, set... in tree form for easy readability; hover over variables to see their values.

- Auto dry run: automatically runs each line with the Back button to review previous steps.

🧠 Code comfortably

- Code suggestions and error reporting as you type

- Code formatting with AStyle (Ctrl+Shift+A), custom snippets and templates.

- Checkpoints save different versions of the code, so you can retrieve deleted ones.

- Auto-save, detects if the file has been modified externally, auto-links .cpp files when including custom headers.

- Double-clicking .cpp files in Explorer opens them directly in Sameko.
