Assignment 4 – Expression Parser CAP6938 Due: 10/25/08 11:59pm The focus of this fourth assignment is to learn the intricacies of creating a 2D parsing system for recognizing mathematical expressions. This is the second part of a two part assignment where you will be creating a simple pen-based calculator. This assignment requires you to take recognized symbols and understand the spatial relationships between them. This understanding will let you create parse trees for mathematical expressions that can be evaluated using simple tree traversal. Requirements Your expression parser must be able to take a list of recognized symbols and their bounding boxes and output a parse tree so the expressions you write can be evaluated. Your parse should support addition, subtraction, multiplication, fractions, superscripts (one level only), square roots, and the equal sign. Examples of some expressions your expression recognizer should be able to handle include:

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
