Simple RPN (reverse polish notation) calculator

Introduction

RPN (reverse polish notation) Calculator in C++20

This project is a C++ implementation of a Reverse Polish Notation (RPN) calculator. The calculator reads arithmetic expressions, converts them from infix notation to postfix notation (RPN), and evaluates the result.

  Multiplication	x * y
  Division	x / y
  Power	x ^ y
  Modulus	x mod y
  Unary plus	+x
  Unary minus	-x
