🚀 SPCC Code Repository

Hey there! 👋 Welcome to my compiler construction repo where I keep all my college assignment code.

This is my personal collection of lexers, parsers, and other compiler components created for my Systems Programming and Compiler Construction course.

📂 What's Inside

This repo contains:

Lex Codes

• Charcount - Character counting utility
• Count - Counts characters, words, etc.
• Hello - Generalized hello greeting
• Lexical_Analyzer - For tokenizing input code
• Personal - Personalized hello based on user's name input
• Vowel - Identifies if character input is vowel or consonant
• Word - Identifies if input is word or number

Parsing & Syntax Analysis

• Parser - Basic parsing implementation
• LL(1) - LL(1) parsing table implementation
• Left_Recursion - Handles left recursion elimination
• Lexical_Analyzer - Lexical analysis implementation

Macro Processing & Assembly

• Macroprocessor - Handles macro expansions
• Assembler(Pass-1) & Assembler(Pass-2) - Two-pass assembler implementation

Other Components

• First(Static_Input) & First(User_Input) - Calculates FIRST sets for given grammar
• Follow(Static_Input) & Follow(User_Input) - Calculates FOLLOW sets for given grammar
• First_Follow - Combined implementation
• TAC - Three Address Code generation
• Code_Optimization - Optimized code for given TAC

🚦 How to Run

For Java files:

# Compile the Java file
javac Filename.java

# Run the compiled program
java Filename

For Lex files:

# Generate C code from Lex file
flex Filename.lex

# Compile the generated C code
gcc lex.yy.c -lfl

# Run the compiled program
./a.out
