INCS Lab Programs

This repository contains the lab programs for the Compiler Design and System Software (CDSS) subject. The programs include implementations using Lex, Yacc, and C language. These are the practical exercises covered during the Compiler Design Lab sessions.

Contents

• Lex Programs: Programs written in Lex for lexical analysis.
• Yacc Programs: Programs that use Yacc for parsing, along with Lex for lexical analysis.
• C Programs: Various C programs related to Compiler Design concepts.

Directory Structure

The repository is organized as follows:

/lex/ lex_program1.l lex_program2.l … /yacc/ yacc_program1.y yacc_program2.y … /c/ program1.c program2.c …

Each directory contains the respective source files:

• /lex/: Contains Lex source files (.l).
• /yacc/: Contains Yacc source files (.y) and associated Lex files.
• /c/: Contains C programs.

How to Compile and Run

Lex Programs

1. Navigate to the lex/ directory:

   cd lex

2. Compile the Lex program:

   lex lex_program1.l
   gcc lex.yy.c -o lex_program1

3. Run the Lex program:

   ./lex_program1

Yacc Programs

1. Navigate to the yacc/ directory:

   cd yacc

2. Compile the Yacc program along with its Lex file:

   yacc -d yacc_program1.y
   lex lex_file.l
   gcc y.tab.c lex.yy.c -o yacc_program1

3. Run the Yacc program:

   ./yacc_program1

C Programs

1. Navigate to the c/ directory:

   cd c

2. Compile the C program:

   gcc program1.c -o program1

3. Run the C program:

   ./program1

Requirements

• Lex: A tool for generating lexical analyzers.
• Yacc: A tool for generating parsers.
• GCC: A compiler for C language.

Make sure these tools are installed on your system to compile and run the programs.
