#pragma overce
Specifies That The File Will Be Included (Opened) Only BY The Compiler In A Build. This Can Reduce Build Times As The Compiler Will NOT OPEN AND Read The File After The First #include of the Module.
Specifies that the current file is only included (or open) once, so that the built-in time is reduced, because after adding #pragma onCE, the compiler will not open after opening or reading the first #include module. Or read the same #include module that will appear. 201,
