An Editor window opens with menus optimized for use in C++ programming. 

The Editor runs certain macros when loading or creating a file, depending on the type of file being loaded or created. Because you specified a C++ language profile, the Editor ran macro profiles for a C++ program. The same profiles are also run if you load an existing file with a .cpp filename extension. This feature customizes the Editor by adding menu selections useful to C++ programmers. It also starts the C++ language parser, which highlights specific parts of a C++ program with distinctive colors and text effects that can be used to identify them.
