?: - Conditional operator
Very useful e.g. to replace
if(Sex) mes "..."; else mes "...";
clauses with simple
mes "Welcome, " + (Sex?"Mr.":"Mrs.") + " " + strcharinfo(0);
or to replace any other simple if-else clauses. It might be worth
mentioning that ?: has low priority and has to be enclosed with
parenthesis in most (if not all) cases.
