#ifndef EVALUATOR_H #define EVALUATOR_H #include using std::string; double Evaluate(const string& postfix, bool& error); #endif #include "evaluator.h" double Evaluate(const string& postfix, bool&...

This lab concerns the coding of a program that evaluates postfix expressions using a stack.

Additionally, this lab will help you understand the use of STL classes as the
stack
class and possibly the
queue
class.

Furthermore, this assignment expects you tocompileandrunfrom the command line.
