Not sure if anyone is even on these forums anymore... BUt i worked with the code some more and kind of chnaged everything around and now i have this..

Code:
#include <iostream>
#include <string>
using namespace std;



class stack
{
public:
       stack ();
       stack (int n);
       void push (char x);
       char pop ();
       bool isempty ();
       bool isfull ();

private:
       int TOP;
       char *storage;
       int size;
};

stack::stack()
{
	   storage = new char [28];
	   TOP=-1;
}

stack::stack(int n)
{
       size = n;
       storage = new char [size];
       TOP = -1;
}

bool stack::isempty() 
{
       return TOP == -1;
}

bool stack::isfull() 
{
       return TOP == size - 1;
}

void stack::push(char x) 
{
       if (isfull())
               cout << "I'm sorry, the stack is currently full." << endl;
       else
               storage[++TOP] = x;
}

char stack::pop() 
{
	   char b;
	if (isempty())
               cout << "I'm sorry, the stack is currently empty." << endl;
       else
   
		   b = storage [TOP--];
			return b;
}

void main()
{
	string x;
	int i = 0;
	stack stackone;
	stack stacktwo;
	stack stackthree;
	cout<<"Please enter a word or phrase:"<<endl;
	getline(cin, x);

	while (i< x.length()-1)
	{
		if(x[i]>='a'&&x[i]<='z'||(x[i]>='A'&&x[i]<='Z'))
			stackone.push(x[i]);
			stacktwo.push(x[i]);
			i++;
	}

	
	while (!stackone.isempty()&&stackone.pop()==stackthree.pop());
	{
		if(stackone.isempty())
			cout<<"This is a palindrome."<<endl;
		else
			cout<<"This is not a palindrome."<<endl;
	}



}

But everything just puts out, This is not a palindrome, and for some reason it posts the stack is empty like 4 times and i cant fiugre out why
