Q. Sometimes it is necessary to modify the syntax of a programming language. This is done by changing the CFG that the language uses. What changes would have to be made to ac's CFG (Figure) to implement the following changes?
(a) All ac programs must contain at least one statement.(b) All integer declarations must precede all float declarations.(c) The first statement in any ac program must be an assignment statement.
Suppose f is a function that returns the result of reversing the string of symbols given as its input, and g. What ambiguity exists in the statement x?
Use undecidability of ALLCFG to illustrate that following problem is also undecidable: Given PDA M1 and FA M2, is L(M1) = L(M2)?
