Compilation - semantic parser -- 4

The goal here is to extend a program that already implements lexical and syntax analysis , and to add a new capability – semantic analysis. Main issues to be covered here are: - Type checking - Scope analysis Semantic actions to be added to the grammar to achieve these goals will need to work with semantic attributes. Implementation should properly address this issue. (the semantic rules for the project language will be provided) Your code should be properly documented ! You also have to perform: 1. Implementation of symbol table. 2. Define and implement a syntax-directed scheme (combining the grammar rules and semantic actions) that allows to perform type checking and scope checking. type and scope checking 3. Error handling (Environment- visual studio 2015- must!)
