- Codeforces - join the UCLA Codeforces Group
- VS Code is a popular free and easy to use editor, and the C++ plugin is excellent.
- Windows Subsystem for Linux is a great way to get the g++ C++ compiler on your Windows computer, integrates with VS Code, and will come in handy for UCLA CS classes like 35L.
- Alternately, on Windows you will need to install Visual Studio
- Mac environment setup
- If you haven't compiled c++ code on your mac before, you will need to install clang, a c++ compiler. You can do so by running the
xcode-select --installcommand on terminal, or downloading Xcode from the app store - Download VS Code for Mac, the superior IDE
- Add the C++ plugin in VSCode
- For more detailed instructions on this setup process, check out this post.
- If you haven't compiled c++ code on your mac before, you will need to install clang, a c++ compiler. You can do so by running the
- Headers on Mac
- Make sure to include the appropriate header files at the top of your cpp file. You can copy them from the template file in this directory.
- A commonly method to include the entire standard library in one line is including the bits/stdc++.h header file but this is not available on mac.
- Repl.it can be used for quick development if you don't want to go through the setup steps (although we encourage you to set up a local environment). You can access a code editor, compiler, and shell without any setup.
