CSC207 Mini-Project 2: Fraction Calculators

Author: Lydia Ye

Date: Sept. 17 2023

This repository contains programs (in Java) for building an interactive calculator and a quick calculator that uses fractions as their basic numeirc type and include registers.

Project Overview

This project has the following classes:

• BigFraction.java includes the implementation of fraction data type.
• BFCalculator.java generates a simple calculator for arithmetic expressions including fractions and integers. Specifically, it provides two (non-static) methods for the calculator:
  • evaluate(String exp) which evaluate an arithmetic expression, ignoring priority,
  • store(char register) which store the last value computed in the named register.
• Interactivecalculator.java provides a main method that repeatedly reads a line the user types, use a BFCalculator to compute the result, and print the result for the user.
• QuickCalculator.java provide a main method that takes the expressions from the command line and then print out the results.
