Using C++ both online and locally (currently for Mac only).
Running C++ both online and locally.
<!-- END DESCRIPTION -->
## Running Online
# Running C++ Online
* [OnlineGDB](https://www.onlinegdb.com/)
* online compiler with an embedded GDB debugger
* can be buggy sometimes
* supports files and file I/O
* [CSAcademy](https://csacademy.com/workspace/)
* pretty nice (unless you get "Estimated Queue Time: ...")
* [Ideone](http://ideone.com/) (used this for a while ...)
* okay with an ad blocker
* make sure your code is not public
* sometimes randomly erases your code when you first create it (so get in the habit of copying your code before creating it!)
* [OnlineGDB](https://www.onlinegdb.com/)
* compiler and debugger tool
Of course, you can't use File I/O on these websites (or do a lot of other stuff ...).
Of course, you can't use file I/O on these websites (except for OnlineGDB) and they are often quite limited.
# Using C++ Locally (on Mac)
# Running C++ Locally
## On Mac
[Clang](https://en.wikipedia.org/wiki/Clang) is the default compiler for Mac OS X, but you should use [G++](https://en.wikipedia.org/wiki/GNU_Compiler_Collection).
## Installation
### Installation
Open **Terminal**. First, familiarize yourself with some basic commands given [here](https://blog.teamtreehouse.com/introduction-to-the-mac-os-x-command-line).

## Compiling & Running C++ via Terminal
## 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.
### 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.
Add MinGW to PATH: https://www.rose-hulman.edu/class/csse/resources/MinGW/installation.htm

## Text Editors
I mostly just use sublime text.
Again, many options.
