stack problem: print after pop function

[george_ya]

have a problem with my program. It should be program that recognize palindome through the stack. Everything works great, only thing that don't work is printing stacks(original and reversed) after the funcion is done. Here is my entire code, and the problem is at case d and e:

#include <iostream>

using namespace std;


const int MAXSTACK = 21;
class stack {
private:
    int  stop;  
    char stk[MAXSTACK];
public:
    stack();
    ~stack();
    stack(const stack& s);
    void push(const char c);
    char pop();
    char top(void);
    int  emptystack(void);
    int  fullstack(void);
    void stack_print(void);
    int stack::create(void);
};
stack::stack()
{
    stop = 0;
}
stack::~stack() { }  
stack::stack(const stack& s)
{
    stop = s.stop;
    strcpy(stk,s.stk);
}
void stack::push(const char c)
{
    stk[stop++] = c;
}
char stack::pop()
{
    return stop--;
}
char stack::top(void)
{
    return stk[stop - 1];
}
int  stack::emptystack(void)
{
    return !stop; 
}
int  stack::fullstack(void)
{
    return stop == MAXSTACK;
}
void stack::stack_print(void)
{
    for (int i=0; i<stop; i++)
        cout<<stk[i];
    cout<<endl;
}
int  stack::create(void)
{
    return !stop; 
}
char menu()
{

    char volba;

    cout<<"\n";
    cout<<" **********.\n";
    cout<<"\n";
    cout<<" a ... make new containers\n";
    cout<<" b ... delete content\n";
    cout<<" c ... enter string\n";
    cout<<" d ... print on screen first stack\n";
    cout<<" e ...  print on screen first stack\n";
    cout<<" f ... is it palindrom\n";
    cout<<" x ... exit\n";
    cout<<"\n your choice : ";

    cin >>  volba;
    return volba;
}
int main() {
    char  palindrome[MAXSTACK]; 
    char volba;
    stack original,reversed;
    int   stackitems = 0,i;
    //cin.getline(palindrome,MAXSTACK);
    do{
        volba = menu();
        switch (volba)
        {
        case'a':
            {
                original.create();
                reversed.create();
                cout<<"done'";
                break;
            }
        case'b':
            {
            original.emptystack();
            reversed.emptystack();
            cout<<"empty";
            break;
            }
        case'c':
            {
                cout<<"enter your string"<<endl;
            cin.get();
            //cin.get();
            cin.getline(palindrome,MAXSTACK);

        }
            original.stack_print();

        break;
            }
        case'd':
            {
                original.~stack();

            original.pop();
        }
        reversed.stack_print();

            reversed.push(original.top());
            original.pop();
        }


        if (stackitems % 2)
            original.pop();

        while (!original.emptystack()) {
            if (original.top() != reversed.top()) break;
            original.pop(); reversed.pop();
        }
        if (original.emptystack())
            cout << "it is palindrom\n";
        else
            cout << "not palindrom\n";

        break;

            }
        default:cout<<"!??!";


        }
    } while(volba!='x');
}

this destutctor thing was just something i tried, but didn't work

Whats the error you get? If everything else works fine, from a brief glance it should work.

One change of code that you can do:

from

stack2.push(stack1.top())
stack1.pop()

to this

stack2.push(stack1.pop())

It doesn't do anything different, but I always find it easier to look at.
