Question

here are my two classes:

#ifndef ISTACK_H
#define ISTACK_H

template
class IStack
{
public:


virtual bool isEmpty() const = 0;

virtual void push(const T& val) = 0;

virtual void pop() = 0;

virtual const T& top() const = 0;

};

#endif

--------------------------------------

#ifndef LISTSTACK_H
#define LISTSTACK_H
#include "IStack.h"
template
struct StackItem
{
T value;

StackItem *next;
};

template
class ListStack: public virtual IStack
{
   public:


   private:

};

#endif

when i try to compile these two classe, i always get an error saying expected class-name before

Replace

#include "IStack.h"

with

class IStack;
