A mini C compiler developed using Lex and Yacc for:

• Structures
• Switch
• While

Phases implemented:

1. Lexical Analysis
2. Syntax Analysis
3. Semantic Analysis
4. Intermediate Code Generation (ICG) in Three Address Code form

Features:

• Symbol Table generation
• Intermediate code is stored in Quadruples format

Errors handled:

• Undeclared variables
• Re-declaration of variables within the same scope
• Type mismatch

Optimizations:

• Constant folding
• Constant propogation
• Loop invariant code identification
• Dead code identification
