Howdy.
when I practise something about reference I figure out we could not declare a reference with more than 1 line, otherwise we would get an error.
we could:
but we couldnt:PHP Code:
int r;
int & ref=r;
Because I know not much about reference and something relatively, so, anyone would give some information about others which are suitable for this rule ?PHP Code:
int r;
int & ref;
ref=r;
thanx in advance~
