1. It is a simple program that that parses a simple expression grammar.
The grammar:
P ---> E '$'
E ---> T { ('+' '-') T }
T ---> F { ('/' '*') F }
F ---> '(' E ')' | digit | letter or in BNF
P ---> E '$'
E ---> E + T | E - T | T
T ---> T * F | T / F | F
F ---> '(' E ')' | digit | letter
Your task is to modify the code to add exponentiation and modulus operations
To add these functions we will change the Grammar to be the following:
P ---> E '$'
E ---> E + T | E - T | T
T ---> T * F | T / F | F
F ---> P ^ F | P
P ---> '(' E ')' | digit | letter
The grammars are very similar but the new grammar but has a a minor change to TERM for
modulus a rewrite of FACTOR to handle exponent operation and a completely new method
called PRIMARY that does what the old FACTOR did
To add the modulus you will need to add the modulus operator '%' character
To add the power (exponentiation) operation you will need to again add a character ('^') and then
rewrite the FACTOR NEW method for PRIMARY Comment your code. You should add a
comment ALL the line you add or modify (required) You must use the given code and you are to
change as little as possible (don't rewrite the whole thing or add any additional functionality)
