# Running C++ Locally
## On Windows
Like Windows in general, you have a lot of options for running C++.
The easiest option is to use an IDE such as [Codeblocks](http://www.codeblocks.org/) or [Visual Studio](https://visualstudio.microsoft.com/vs/) because they often have C++ support already built-in. See the IDEs section below for more information.
However, you can also use [MinGW](http://mingw.org/) if you prefer compiling and running C++ using the command line. Another good option is Windows Subsystem for Linux (WSL) which is what I personally use, although it may be more difficult to properly set up.
### Installing MinGW
First, download and run the [MinGW installer](https://osdn.net/projects/mingw/downloads/68260/mingw-get-setup.exe/). Once it's installed, open the MinGW Installation Manager, click on Basic Setup on the left, and select `mingw32-gcc-g++-bin` for installation.

### Installing WSL

## On Mac
[Clang](https://en.wikipedia.org/wiki/Clang) is the default compiler for Mac OS X, but you should use [GCC](https://en.wikipedia.org/wiki/GNU_Compiler_Collection)'s g++ since that's what [USACO](http://www.usaco.org/index.php?page=instructions) uses to compile your code.
