The language L, defined by the following grammar allows use of real or integer data in expressions and assignment statements.
(assign-stmt):: = (LHS):= (E) (E) :: = (E) + (T) | (T) (T) :: = (T) * (V) | (V) (V) :: = id | ((E)) (LHS) :: = id
It is required to convert expression and assignment strings of L into postfix strings that use the type-specific operators (+, i), (+, r), (*, i), (*, r), (:=, i) and (:=, r).
Write a syntax directed translation scheme to convert expression and assignment strings into the post-fix form. You may assume that the name and type of a variable can be obtained by making the function calls ‘give-type (id)’ and ‘give-name (id)’ respectively.
