calculator-task

Brief

This project implements basic infix calculator, with extendability in mind. Unary and binary operators and functions are supported.

Contents

• Infix to postfix conversion implementation
• Token object, which represents numbers, operators etc. Attempted to be extendable
• basic implementation of vector, stack and smart pointers residing in util directory. It reappears in next projects and may not be synced

Usage

postfix_converter_t Class

convert(const std::string& in_str) - converts infix arithmetic expression to evaluable postfix_expr_t
Throws, if there is syntax error (e.g. misplaced operators, brackets etc) or unknown token is present

postfix_expr_t

evaluate() - evaluates expression

Future Work

A refactoring is urgently needed in

• General files structure
• Moving definition and renaming of classes and functions
• Rework extendability, to make it as smooth as possible
