3. Given the following BNIF cond_expr>expr>? : id a) Define an attribute grammar that enforces the following rules: a) id's type can be bool, int, or float. b) Operands of+ must be numeric and of the same type. c) The type of + is the type of its operands. d) The first operand of?: must be of bool and the second and third must be of the same type. e) The type of ?: is the type of its second and third operands. Given your attribute grammar, draw a decorated parse tree for "id ? id: id + id" assuming that the first id is of type bool and the rest are of type int. b)
