Conditional operator

Ternary ?: is the conditional operator. It works like an if-then-else statement but can safely be embedded within other operations and functions:

                     test_expr ? if_true_expr : if_false_expr

If the test_expr is true, only the if_true_expr is evaluated. Otherwise, only the if_false_expr is evaluated. Either way, the value of the evaluated expression becomes the value of the entire expression.
