consider the statement "x = (a > b) ? a : b"; then the value of x is 27, if a = 18 and b = 27.
-
True

False
To solve this question, the user needs to know about Conditional (ternary) Operator.
The conditional operator (also known as the ternary operator) is a shorthand way of expressing a conditional statement. It takes three operands and is denoted as condition ? true_expression : false_expression. The condition is evaluated first, and if it is true, the expression before the colon (:) is evaluated and its value is returned. If the condition is false, the expression after the colon is evaluated and its value is returned.
In the given statement, x is assigned the value of a if a is greater than b, and b otherwise.
Now let's substitute the given values of a and b:
x = (a > b) ? a : b
x = (18 > 27) ? 18 : 27
Since 18 is not greater than 27, the condition a > b is false and x is assigned the value of b, which is 27.
Therefore, the statement "x = (a > b) ? a : b; then the value of x is 27, if a = 18 and b = 27" is true.
The Answer is: A
The ternary operator (a > b) ? a : b evaluates the condition first: is a greater than b? Here a = 18 and b = 27, so 18 > 27 is false, meaning the expression takes the value after the colon, which is b. Since b = 27, x becomes 27, matching the statement, so it is True.
