arithmetic-calculator

A C++-based expression tree solution to an arithmetic parser.

About

Goal: To create and evaluate an arithmetic parser without use of Shunting Yard algorithm.

Solution: Implement object-oriented-heavy approach using Composite, Interpreter, Builder, Visitor, and Fascade design patterns.

Overall TODOs:

• implement memory-critical destructors
• implement strict user input handling
• implement subtraction and division operators
• unary operators
• formal function and class headers for entire project

• perhaps consolidate the expression and builder composites

  Usage

  arithmetic_calculator.cpp [expression]

  or use loop when run w/o any c-line args.
  Only acceptable input for expression is * + ( ) [0-9]+
  max 9999 per literal, all else is undefined.
