YASL Interpreter Your task for this project will be to write an interpreter for YASL. Since we will want to use the console input/output for the interpreted program to interact with the user, the interpreter will need to take the name of the YASL source file as a command-line parameter. For example, suppose that we […]

Recursive-Descent Parser Your task for this stage of the project is to construct a recursive-descent parser for the entire YASL language. The output will be a formatted representation of the resulting abstract syntax tree. Sample Run Here is a sample YASL program that shows most of the language: // This program shows just about all
