Which combination of the integer variables $x, y$ and $z$ makes the variable $a$ get the value $4$ in the following expression?
$$a=(x > y)?((x > z) ?x:z): ((y > z) ?y:z)$$
Note: " ? : " operator associativity is Right to Left. Only Assignment, Unary & ?: operator are right to left. Rest all are left to right. http://www.difranco.net/compsci/C_Operator_Precedence_Table.htm
Using option A : x=3, y=4, z=2
a=(3>4)? No
therefore don't evaluate the first part and check second part ((y>z)?y:z)
(4>2)? Yes
a= value of y =4
Answer is (A) x=3, y=4, z=2
