Implement symbol table

Reference no: EM133141578

Question:

Project you are going to generate code in C language.

How the code generation takes place.

B. You will also implement symbol table. I am uploading a small write up on symbol table. Also I did explain it in the class how symbol table works

C. After symbol table implementation, your compiler can catch errors.

Implement catching at least 3 errors - for example using undeclared variable, type mismtach etc etc.

Submit all the files .....Y, .c files (.c and .h written by you and npot generated by bison or flex)

Finally, signup to demo your project. I will ask the grader to prepare a signup sheet on google.

Please read the following before you run the program

1. List of files
================

Filename Description
--------------------------------------------------------------------------------------------------------------------
lexer.l => code for lexical analyzer
semantic.y => code for semantic analysis

types.h => C header (interface) for type checking
types.c => C source for type checking

symbol_table.h => C header (interface) for symbol table
symbol_table.c => C source for symbol table

makefile => a make file for compiling the sources

Tests/test_success => test for success case
Tests/test_error => test for error case

2. Running the parser
=======================

Fire the following commands from terminal:

make

Optionally, you can build the source by executing

bison -d parser.y // generates parser.tab.c and parser.tab.h for use in lexer.l
flex lexer.l // this creates a lex.yy.c file

gcc parser.tab.c lex.yy.c symbol_table.c hash_table.c -o parser // links lex.yy.c, symbol_table.c and hash_table.c to parser.tab.c and generates a parser

You can then run the parser as follows:

./parser

Alternatively, run the scanner with given test cases:
make test_success // for success case
make test_error // for error case

3. NOTES
========

The program is designed using Flex 2.5.35 and bison 3.0.2 on Ubuntu 14.04 machine.

To install both flex and bison run:

sudo apt-get install flex
sudo apt-get install bison

N0te: Need help on part A. not able to generate C code. B & C working fine.
