Here it is set to the active file folder ${fileDirname} and active filename without an extension ${fileBasenameNoExtension}, which if helloworld.cpp is the active file will be helloworld. This will advance program execution to the first line of the for loop, and skip over all the internal function calls within the vector and string classes that are invoked when the msg variable is created and initialized. As you go through the tutorial, you will create three files in a .vscode folder in the workspace: In the File Explorer title bar, select New File and name the file helloworld.cpp. Choose C/C++: g++ build active file.
