que.print is not working and I cannot figure out why not
I posted a lot of code because I cannot figure out where the error is, I think it is in que.cpp, but I am nto sure what is wrong.
Here is the main
#include "Stack.h"
#include "Que.h"
#include<string>
#include <iostream>
#include <fstream>
using namespace std;
int main()
{
string file;
Stack stack;
Que que;
ifstream inputFile;
inputFile.open("text.txt");
while(inputFile.good())
{
inputFile >> file;
stack.push(file);
que.add(file);
}
stack.printStack();
que.print(); //not working
return 0;
}here is the h file
#ifndef QUEUE

void printHelper(Node *);
public:

~Que();
void add(string);
string remove();
bool isEmpty() const;
void operator=(const Que &);
void print();
};
#endifhere is the cpp file for que
