Consider the following parse tree for the expression a#b$c$d#e#f, involving two binary operators $ and #.
Which one of the following is correct for the given parse tree?
(A) $ has higher precedence and is left associative; # is right associative
(B) # has higher precedence and is left associative; $ is right associative
(C) $ has higher precedence and is left associative; # is left associative
(D) # has higher precedence and is right associative; $ is left associative
Answer: (A)
Explanation: Since $ will be evaluated first, so has higher precedence with left associativity. Whereas # is right associative. In d#e#f, e#f will be evaluated first (refer given parse tree).
Therefore, option (A) is Correct.
