CS 4110 Compiler Design - Project Phase 1. Lexical analysis Total Points: 15 In this project, you need to implement a compiler for a language defined here. The programming language you need to use is C or C++ (and the language defined by the corresponding tools). The project includes two phases, lexical analysis, and syntax analysis. In the following, we first define the language syntax a nd tokens. The definitions are given in BNF form. 1 Language Definitions 1.1 Syntax Definitions program : .
