  3. Ternary Operator
  1. The ? operator is often used to replace certain types of if-then-else constructions.
  2. The ? is called a ternary operator because it requires three operands.

It takes the general form

Exp1 ? Exp2 : Exp3;
  1. where Exp1 is a bool expression, and Exp2 and Exp3 are expressions.
  2. The type of Exp2 and Exp3 must be the same.

The value of a ? expression is determined like this:

  1. Exp1 is evaluated.
  2. If it is true, then Exp2 is evaluated and becomes the value of the entire ? expression.
  3. If Exp1 is false, then Exp3 is evaluated, and its value becomes the value of the expression.
