Hi all my first post, so here goes ... Most sources (including RHE) state that an identifier must begin with a letter, dollar sign ($) or an underscore(_). I'm using the � (pound) sign and it works fine as follows. int �anInt = 1; I also believe that other currency symbols (I read this somewhere a long time ago) will work equally as well. Can anyone explain this? If this question were to come up in the exam, how would you answer it?
