    can you highlight the lines (color them red or something and comment out) where the errors occur. Some look pretty trivial.

    some entropy with that sink? entropysink.com

    there are two cardinal sins from which all others spring: Impatience and Laziness. - franz kafka

    change:
    //contructor
    Stack();
    to:
    //contructor
    Stack::Stack() {}

    add
    //constructor
    Stack::Stack(int size) {
    // fill in details here
    }

    change:
    bool IsDrome(char* c)
    {
    Stack S;

    to:
    bool IsDrome(char* c)
    {
    Stack S(strlen(c) * sizeof(char));


    that should get you started.

    Just thought I'd point out:
    Code:
    #include <iostream>
    #include <string>   //Was string.h
    #include <windows.h>
    #include <cstdio>  //Was stdio.h
    Just Google It. √

    Don't you just love posts that don't say anything at all? Just throw a bunch of code up there, no questions, no description, nothing, and expect you to fix it...
