While there is a massive number of IDEs support C++, not all of them are created equal. We'll be giving preference to the modern ones and/or the ones that you'll be most likely to use in your professional practice. They also happen to be the easiest to install on each respective platform:
| Platform | Recommended IDEs |
|---|---|
| macOS | Xcode, Visual Studio Code |
| Windows | Visual Studio Community, Visual Studio Code |
| GNU/Linux | Visual Studio Code |
Similarly to the IDEs, there are typically several C++ compilers available for every major OS platform. We'll be using the "default" compiler for each platform — the one that's distributed by the operating system's vendor as a part of their IDE/development toolset:
| Platform | Compiler | Installation |
|---|---|---|
| Mac | clang | Installed with Xcode; a standalone download is available here (you'll be asked to log in with your Apple ID; search for "command line tools" once in). |
| Windows | Microsoft C/C++ compiler | Installed with Visual Studio; a standalone download is available here under Tools for Visual Studio 2017 > Build Tools for Visual Studio 2017. |
| Linux | gcc | Included in all distribution; open a terminal and run sudo apt install build-essential if it's not installed by default. |
Most recent versions of the compilers listed above support all or most of the C++17 standard. You do have to explicitly enable C++17 support, though:
| Compiler | Enabling C++17 support |
|---|---|
| clang, gcc | Add -std=c++17 to the compiler flags, e.g. clang++ -std=c++17 main.cpp. |
| Microsoft C/C++ compiler | See How to enable C++17 compiling in Visual Studio, or manually add /std:c++17 to the compiler flags, e.g. cl /std:c++17 main.cpp. |
Xcode is Apple's IDE for developing on Mac. It supports C++ out-of-the-box and comes with Apple version of clang compiler.

Visual Studio Code (VS Code) is a free, open source, customizable editor from Microsoft available on all major platforms. It includes first-class support for C++, including debugging, syntax highlighting, code completion, linting and refactoring. It also comes with a wealth of extensions that can be installed to further enhance the editor's functionality, effectively making it a full-fledged, extensible IDE.
