Question

sample code:

file: LinkedStack.h

#include "NodeType.h"

#ifndef LINKEDSTACK_H
#define LINKEDSTACK_H

template <class ItemType>
class LinkedStack {
public:
    NodeType topPtr;
};

file: NodeType.h

#ifndef NODETYPE_H
#define NODETYPE_H

template <class ItemType>
class NodeType {
public:

    ItemType info;
    NodeType *nextElement;

};

#endif  /* NODETYPE_H */

file: main.cpp

#include "NodeType.h"
#include "LinkedStack.h"

using namespace std;

int main(int argc, char** argv) {

    return 0;
}

When I run this, I keep getting:

LinkedStack.h:20: error: `NodeType’ does not name a type

However NodeType is already defined and included?

Answer 1

NodeType is a template. Change to:

NodeType<ItemType> topPtr;
