/*
Name: Renee Iinuma, Kyle Lee, and Wesley Kepke.
File: symbolTable.cpp
Created: September 28, 2015
Last Modified: October 27, 2015
Class: CS 460 (Compiler Construction)
This is the input file to Bison that will be used in the front end of our
compiler.
The parser is responsible for two main tasks:
1. Checking for syntax analysis as the tokens are passed from the lexer to the
parser.
2. Performing the appropriate semantic action for each production of the ANSI C
grammar.
This file is used to created cParser.tab.h, the header file containing all of
the token declarations that will be used in the lexer.
