3. Consider the attribute grammar for type checking of assignment statements given in the Supplement. POUUUNUUU a. Suppose typeLookup('a') = float, typeLookup('b') = int, and typeLookup(*c) = long. Sketch the decorated parse tree for the following assignment statement: a = b + c b. According to the predicate given in the Supplement, is this assignment statement type- correct? Explain your answer. 3. Consider the attribute grammar for type checking of assignment statements given in the Supplement. POUUUNUUU a.
