Showing the Proper Parse Tree for ** Grammar A + B * C A ** B + C <expr> <expr> <term> + | <expr> - <term> | <term> <term> <term> * <factor> | <term> / <factor> | <factor> <factor> <exp> ** <factor> | <exp> <exp> ( <expr> ) | <id> <id> A | B | C | … Try A + (B * C) / D just to get used to this new grammar. Did it come out right? Then try A ** B ** C. Which portion was the lowest on the tree? Answersb: FYI Section Who needs to know and understand your language? there are many people needed in the development of a new programming language, but who are they?? Answers: Language recognizers and Generators Language Recognizers (also called Finite State Machines!!) accept a Language like a Machine. The Machines take a string as input. The Machines will accept the input if when run, the Machine stops at an accept state. Otherwise the input is rejected. If a Machine M recognizes all strings in Language L, and accepts input provided by a given string S, M is said to accept S.
