Phases of Compiler

A Simple Implementation of Compiler Phases

This project demonstrates a basic implementation of several phases of a compiler: lexical analysis, syntax analysis, and translation from infix to postfix notation.

Introduction

This project showcases a simplified version of a compiler that processes an input expression, validates its syntax, constructs a parse tree, and converts the expression from infix to postfix notation. The implementation covers:

• Lexical Analysis: Tokenizing the input.
• Syntax Analysis: Validating and parsing the expression into a parse tree.
• Infix to Postfix Conversion: Translating infix expressions to postfix notation.

Demonstration
