Quick Way to Compile C++ on Mac 2020 - G++ Guide [No XCode]
To use Eclipse for C/C++ programming, you need a C/C++ compiler. On Windows, you could install either MinGW GCC or Cygwin GCC. Choose MinGW if you are not sure, because MinGW is lighter and easier to install, but having less features.
In OS X, GCC is part of Xcode's command tools, so first, open the Mac App Store and install Xcode for free. Then, open Xcode, go to Xcode menu (on the menu bar) > Preferences > Downloads, and install Command Line Tools. You will get commands like gcc, make, purge...
Download Xcode from the Mac App Store (or Apples Developer site https://developer.apple.com/ - you may need to register a free developer account to access the download area). Xcode contains compilers for C / C++ / Objective-C.
Clang is much faster and uses far less memory than GCC. Clang aims to provide extremely clear and concise diagnostics (error and warning messages), and includes support for expressive diagnostics. GCC's warnings are sometimes acceptable, but are often confusing and it does not support expressive diagnostics.
Open terminal and enter clang –version. Clang is the compiler built by Apple to compile C and a bunch of other languages.
If you'd rather use an IDE for C++ development, you can install the devC++ compiler/IDE for windows. Download the exe file from https://bloodshed-dev-c.en.softonic.com/ and follow the instructions there to install it. Installation is pretty straightforward.
Xcode 4.6. 2 uses the Clang C++ compiler frontend with LLVM as backend which is conform to the C++11 standart and uses libc++ as the standart library.

Is Xcode good for C++?
Xcode is a great IDE for C/C++ whether Eclipse, NetBeans that can be configured to build and compile C++ projects. CLion from Jetbrains. It allows you the control over address and value from variables including a good interface.
You will need to go to Project->Clean...,then build your project. This will work, even when your source code does not contain any main method to run as an executable program. The . class files will appear in the bin folder of your project, in your workspace.

An IDE typically contains a code editor, a compiler or interpreter, and a debugger, accessed through a single graphical user interface (GUI). The user writes and edits source code in the code editor. The compiler translates the source code into a readable language that is executable for a computer.
In Eclipse, go to the "File" menu, then "New", then "C++ Project" if it's there. If not, choose "Project", then find "C/C++" in the list of wizards, click the "+" sign to expand it, and choose "C++ Project". A dialog box will ask whether to open the C/C++ perspective. Answer "yes", and remember this decision.
