Question 1

What is y after the following statement is executed?

x = 0;
y = (x > 0) ? 10 : -10;

◦ -10
◦ 0
◦ 20
◦ 10
◦ Illegal expression

Question 2

Analyze the following code fragments that assign a boolean value to the variable even.

Code 1:
if (number % 2 == 0)
even = true;
else
even = false;

Code 2:
even = (number % 2 == 0) ? true: false;

Code 3:
even = number % 2 == 0;

◦ All three are correct, but Code 2 is preferred.
◦ All three are correct, but Code 1 is preferred.
◦ Code 3 has a compile error, because you attempt to assign number to even.
◦ Code 2 has a compile error, because you cannot have true and false literals in the conditional expression.
◦ All three are correct, but Code 3 is preferred.
