the following grammar generates all regular expressions over the alphabet of letters (we have used quotes to surround operators, since the vertical bar is an operator as well as a metasymbol): rexp->rexp “|” rexp | rexp rexp | rexp “*” | “(” rexp “)” | letter a. give a derivation for the regular expression (ab|b)* using this grammar. b. show this grammar is ambiguous c. Rewrite this grammar to establish the correct precendences for the operators. d. What associativity does...

The second project involves completing and extending the C++ program that evaluates statements of an expression language contained in the module 3 case study. The statements of that expression language consist of an arithmetic expression followed by a list of assignments. Assignments are separated from the expression and each other by commas. A semicolon terminates the expression. The arithmetic expressions are fully parenthesized infix expressions containing integer literals and variables. The valid arithmetic operators are +, –, *, /. Tokens...

EVALUATING GENERAL INFIX EXPRESSIONS INTRODUCTION The notation in which we usually write arithmetic expressions is called infix notation; in it, operators are written between their operands: X + Y. Such expressions can be ambiguous; do we add or multiply first in the expression 5 + 3 * 2? Parentheses and rules of precedence and association clarify such ambiguities: multiplication and division take precedence over addition and subtraction, and operators associate from left to right. This project implements and exercises a stack-based algorithm that evaluates...

Please help me with the coding for LL(1)!!
The given grammar was:
P → PL | L
L → N; | M; | C
N → print E
M → print "W"
W → TW | ε
C → if E {P} | if E {P} else {P}
E → (EOE) | V (note: this has a variable O)
O → + | - | * V → 0 | 1 | 2 | 3 (note: this has a terminal...

Infix Expression Evaluator For this project, write a C program that will evaluate an infix expression. The algorithm REQUIRED for this program will use two stacks, an operator stack and a value stack. Both stacks MUST be implemented using a linked list. For this program, you are to write functions for the linked list stacks with the following names: int isEmpty (stack); void push (stack, data); data top (stack); void pop (stack); // return TRUE if the stack has no...
