? : Operator
We've covered conditional operators in the previous sections. : , can be used as an alternative to if... E lse statement. Its general form is as follows:
Exp1 ? Exp2 : Exp3;Exp1, Exp2, and Exp3 are expressions. Note the use and location of the colon.
? T he value of the expression is determined by Exp1. I f Exp1 is true, the value of Exp2 is calculated and the result is the entire ? T he value of the expression. I f Exp1 is false, the value of Exp3 is calculated, and the result is the entire ? The value of the expression.
