No answer
i found it ...
Programmers use the ternary operator " ? "for decision making in place of longer if and else conditional statements.
The ternary operator take three arguments:
1- The first is a comparison argument
2- The second is the result upon a true comparison
3- The third is the result upon a false comparison
It helps to think of the ternary operator as a shorthand way or writing an if-else statement.
Syntax
condition ? value_if_true : value_if_false
The statement evaluates to value_if_true if condition is met, and value_if_false otherwise.
