Expert Solution & Answer
Chapter 3, Problem 9PS
Explanation of Solution
Consider the following grammar in BNF:
<assign> -> <id> = <expr>
<id> —> A|B|C
<expr> -> <expr> + <term> | <term>
<term> -> <term> * <factor> | <factor>
<factor> -> (<expr>)| <id >
The grammar of Example 3.4 to add a unary minus operator that has higher precedence than either + or * are as follows:
<assign> -> <id> = <expr>
<id> —> A|B|C
<expr> -> <expr> + <term> | <term>
<term> -> <term> * <factor> | <factor>

Write a GO grammar expression where:
1. An expression is either an id (you may assume this token has been defined) or a combination of subexpressions using the **, ^ and $ operators
2. ** is a binary infix operator, while ^ is a unary operator that appears before an expression and $ is an operator that appears after an expression
3. ^ has precedence over **, which has precedence over $
4. ** has right-associativity

- a. Eliminate Left Factoring from the grammar above. b. Eliminate Left Recursive from the grammar above if there is any.arrow_forwardFor this exercise, we will work on a regular grammar to recognize a comment in a C++ or Java program. A comment starts with /* and ends with */ and anything else in between can be ignored. We won't consider the case of nested comments. Keep in mind that you can have any number of * characters at the beginning, at the end, and in between. • Write a regular grammar recognizing such comments. • Draw the finite state machine for this grammar. • Draw a table for this grammar such as the ones for table-driver scanners in the class notes and in the book.arrow_forwardUse the grammar you have created in Question 1 for an infix expression and using the technique: Syntax Directed Definition write appropriate semantic rules to convert an infixexpression of that grammar to a prefix expression.Precedence of operators are given below (high to low): ()*, / +, - =Associativity of operators are given below:+, , *, / [Left Associative]= [Right Associative]Taking into account the precedence and the associativity of the operators in this question, if any modification is needed for your grammar in Question 1 to be used in this question, do it.

- 3. Write a correct recursive descent grammar that correctly recognizes arithmetic expressions involving variable, number, + - * / **.

This language consists of strings that have n copies of the letter b preceded by n * 2 copies of the letter a, where n is an odd integer > 0. For example, the strings aab, aaaaaabbb, aaaaaaaaaabbbbb are in the language and the strings a, ab, aaaabb (because there are not an odd number of b's), b, ba are notarrow_forwardWrite a grammar for Boolean expressions , assuming that we already have rules in our grammar for arithmetic expressions . Arithmetic expressions might be simple literals like 3 or 97 or may be more complex syntactic units like (3+x)/4. They evaluate to a number. You needn't concern yourself with their structure; just that they can be used as below. Boolean expressions include the literals TRUE and FALSE; they can be combined with the unary operator ! (meaning NOT) and binary operators && and || (meaning AND and OR). Also, arithmetic expressions can be combined with the following binary operators to form new Boolean expressions: , =, !=. When your grammar is complete, you should be able to derive parse trees for expressions like the following: TRUE || FALSE FALSE && !TRUE 27 = TRUE | FALSEarrow_forward
