Equivalent of #region for C++

The Region keyword is IDE specific and affects rendering in Visual Studio. The nearest equivalent is #pragma Region which is applicable to Visual Studio only .

Code example from MSDN

// pragma_directives_region.cpp
#pragma region Region_1
void Test() {}
void Test2() {}
void Test3() {}
#pragma endregion Region_1

int main() {}

In addition to #pragma region…#pragma endregion for Visual Studio, many IDEs support the following syntax for regions in any {}-delimited, //-commented language:

//{ Region header text.
…
//}

Notable examples include Code::Blocks and FlashDevelop, and any other editor that uses the Scintilla editing component, such as Notepad++, Geany, Komodo Edit, and many more.

There isn't an equivalent in C++. However IDEs should be able to collapse sections.

It is also possible to use something like this:

#pragma region

#pragma endregion A comment about the region.

But probably not very portable
