missing type specifier error

[GGWPBOT]

There is an error in this part of code i cant figure out why and what is the fix for it and it says "missing type specifier - int assumed. Note: C++ does not support default-int":

  template<class ItemType> class Stack
{
private:
	NodeType<ItemType> *topPtr, *tailPtr, *temp;
	int stackLength;

Here is the entire code:

  #include <iostream>
using namespace std;

template<class ItemType> class Stack
{
private:
	NodeType<ItemType> *topPtr, *tailPtr, *temp;
	int stackLength;
	int top;
public:
	Stack()
	{
		top = -1
	};

	void MakeEmpty()
	{
		top = -1
	};

	bool IsEmpty()
	{
		return (top == -1);
	};

	bool IsFull()
	{
		return (top == 5)
	};


	int length()
	{
		return stackLength
	};

	void Print()
	{
		for (; topPtr; topPtr = topPtr->next)
		{
			cout << temp->value << endl;
			temp = temp->next;
		}
	};

	void Push(ItemType x)
	{
		if (IsFull())
		{
			cout << "Stack is full";
			return;
		}
		if (topPtr == NULL)
		{
			topPtr = new NodeType<ItemType>;
			topPtr->info = x;
			tailPtr = topPtr;
			top++;
			length++;
		}
		else
		{
			temp = new NodeType<ItemType>;
			temp->info = x;
			temp->next = NULL;
			tail->next = temp;
			tail = tail->next;
			top++;
			length++;
		}
	};

	void Pop(ItemType &x)
	{
		NodeType<ItemType> *p1=topPtr, *temp1;
		if (top == -1)
		{
			cout << "stack is empty";
				return;
		}
		
		if (x == topPtr->info)
		{
			temp1 = p1;
			topPtr = topPtr->next;
		}

		else
		{
			while (!(x == p1->next)->info)
			{
				p1 = p1->next;
			}
			temp = p1->next;
			p1->next = (p1->next)->next;
		}

		delete temp1;
	};
	
	//~Stack();  // Destructor:  memory for nodes needs to be deallocated
};

template<class ItemType>
struct NodeType
{
	ItemType info;
	NodeType* next;
};





int main()
{

	Stack <int> IntStack;
	int x;
	IntStack.Pop(x);
	IntStack.Push(11);
	IntStack.Push(22);
	cout << "int length 1 = " << IntStack.length() << endl;
	IntStack.Pop(x);
	IntStack.Push(33);
	cout << "int length 2 = " << IntStack.length() << endl;
	cout << "The int stack contains : " << endl;
	IntStack.Print();
	IntStack.Push(44);
	IntStack.Push(55);
	IntStack.Push(66);
	if (IntStack.IsFull() == false)
		cout << "The int stack is not full !" << endl;
	else
		cout << "The int stack is full !" << endl;
	Stack <int> IntStack2(IntStack);
	cout << "The int stack2 contains : " << endl;
	IntStack2.Print();
	IntStack2.MakeEmpty();
	cout << "The int stack3 contains : " << endl;
	IntStack2.Print();


	Stack <float> FloatStack;
	float y;
	FloatStack.Pop(y);
	FloatStack.Push(7.1);
	cout << "float length 1 = " << FloatStack.length() << endl;
	FloatStack.Push(2.3);
	FloatStack.Push(3.1);
	cout << "float length 2 = " << FloatStack.length() << endl;
	FloatStack.Pop(y);

	FloatStack.Print();
	Stack <float> FloatStack2 = FloatStack;
	cout << "The float stack 2 contains:  " << endl;
	FloatStack2.Print();
	FloatStack.MakeEmpty();
	cout << "The float stack 3 contains:  " << endl;
	FloatStack2.Print();


	system("PAUSE");

You need to define NodeType before you define Stack.

Gotcha, thanks alot

[AbstractionAnon]

Simply move lines 104-109 to before line 4.

Lines 13,18,28,34: missing ;

Line 48: value is not a member of NodeType (temp).

Line 59, 69: length is a function. You can't increment it.

Lines 66-67; tail is undefined. Did you mean tailptr?

There are more errors, but I stopped there.
