Overview The purpose of this assignment is to extend the Lexer component of our x language compiler to be able to handle additional tokens, to supplement our understanding of Compilers and Lexical Analysis. You are provided with the Lexer code (in the compiler codebase), which will be automatically cloned into your github repository when you begin the assignment via this github assignment link. Submission Your assignment will be submitted using github. Only the main branch of your repository will be graded. Late submission is determined by the last commit time on the "main" branch. You are required to submit a documentation PDF named "documentation.pdf" in a "documentation" folder at the root of your project. Please refer to the documentation requirements posted on iLearn. Organization and appearance of this document is critical. Please use spelling and grammar checkers - your ability to communicate about software and technology is almost as important as your ability to write software! Requirements The Token class must be updated to include the line number that a token was found (for subsequent error reporting, etc.)
