What This Document Is
This document outlines the first phase of a compiler construction project for an advanced computer science course. Specifically, it details the requirements for building a lexical analyzer – often called a scanner – for the Cool programming language. It’s a core assignment designed to provide hands-on experience with the foundational elements of compiler design. This assignment focuses on the initial stage of transforming source code into a format a computer can understand.
Why This Document Matters
This assignment is crucial for students enrolled in compiler construction courses, or those seeking a deep understanding of how programming languages are processed. It’s particularly relevant for anyone preparing to design and implement their own compilers or interpreters. Successfully completing this phase is essential before moving on to more complex stages like parsing and code generation. It’s best utilized when you’re ready to apply theoretical knowledge to a practical coding challenge.
