C Quiz – 107 | Question 1
Suppose a, b, c and d are int variables. For ternary operator in C ( ? : ), pick the best statement.
(A) a>b ? : ; is valid statement i.e. 2nd and 3rd operands can be empty and they are implicitly replaced with non-zero value at run-time.
(B) a>b ? c=10 : d=10; is valid statement. Based on the value of a and b, either c or d gets assigned the value of 10.
(C) a>b ? (c=10,d=20) : (c=20,d=10); is valid statement. Based on the value of a and b, either c=10,d=20 gets executed or c=20,d=10 gets executed.
(D) All of the above are valid statements for ternary operator.
Explanation: For ternary operator, both 2nd and 3rd operands are necessary. So A) isn’t correct. As per operator precedence, ternary operator has higher precedence over assignment operator. So B) isn’t correct.
