Re: what does this line means? Many thanks

In following formular, exp ? statement1 : statement2 if exp is true, statement1 is excuted, else statement2 is excuted. So it is equivalent to: if( exp ) { statement1 } else { statement2 } If you still want to ask what "?" means, I think it can be "if exp is true".
