actually, you can even store pointers to nothing in memory. you just do:
void x;
void* x_ptr = &x;
then you can use it to invoke functions that take no arguments like this:
voidopen_texteditor(void editor_choice){
// do nothing with the editor_choice because there is only one sensible editoropen_nano();
returnvoid;
}
void favorite_texteditor;
void result = open_texteditor(favorite_texteditor);
print_error_on_bad_result(result);
Including nothing. Actually, depending on the language, multiple types of nothing (null vs uninitialized)

This has made a lot of people very angry and been widely regarded as a bad move.
