That is correct. Comments are converted into spaces before
preprocessing occurs. In practice, it is common for a single
preprocessor program to have two modes of operation, one in which //
starts a comment and one in which it does not. That preprocessor can
then be used for both languages. (Actually other options are needed
too, controlling which digraphs are recognised.)
