I am new to the templates..
I was trying to implement templates in my x programs....
and i am stuck ...
help me...
problem is with the "search" function

when i was not using templates

search function was
Stack::Nodeptr Stack::search(char item)
and worked perfectly fine..
when using templates...
i tried to do..
template <class Dtype>
Stack<Dtype>::Nodeptr Stack<Dtype>::search(Dtype item)

but it doesn't bug...
i have also tried other combination but :(

Program is like this

template <class Dtype>
class Stack
{
	protected:
		struct Node
		{
		 	   Dtype info;
			   Node *link;
  		};
  		typedef Node *Nodeptr;
		Nodeptr front;
	
	public:
		Stack();
		void push(Dtype);
		Dtype pop();
		Dtype peep();
		Nodeptr search(Dtype);
		void display();
		void menu();
};

template <class Dtype>
Stack<Dtype>::Stack()
{
	front=NULL;
}

template <class Dtype>
Dtype Stack<Dtype>::peep()
{
	if(front==NULL) return '\0';
	return front->info;
}

template <class Dtype>
void Stack<Dtype>::push(Dtype data)
{
	Nodeptr temp=new Node;
	temp->info=data;
	
	temp->link=front;
	front=temp;
}

template <class Dtype>
Dtype Stack<Dtype>::pop()
{
	if(front==NULL) return '\0';
	
	Nodeptr temp=front;
	front=front->link;
	
	int r=temp->info;
	delete temp;
	
	return r;
}

/* this guy has the problem
template <class Dtype>
Stack<Dtype>::Nodeptr Stack<Dtype>::search(Dtype item)
{
	Nodeptr traverse=front;
	
	while(traverse!=NULL)
	{
		if(traverse->info==item) return traverse;
		traverse=traverse->link;
	}
 
	return NULL;
}
*/
template <class Dtype>
void Stack<Dtype>::display()
{
	Nodeptr traverse=front;
	
	while(traverse!=NULL)
	{
		cout<<traverse->info<<(char)26;
		traverse=traverse->link;
	}
 
	cout<<(char)237;	
}

template <class Dtype>
void Stack<Dtype>::menu()
{
	Dtype data;
	for(;;)
	{
		cls;
		cout<<"Stack\n"
		<<"\n1. Push"
		<<"\n2. Pop"
		<<"\n3. Peep"
		<<"\n4. Search //problem lies here"
		<<"\n5. Display"
		<<"\n\nEnter your choice: ";
		
		switch(getch())
		{
			case '1':
			case 13:
				cls;
				cout<<"Enter any no: "; cin>>data;
				push(data);
				break;
			
			case '2':
				cls;				
				cout<<pop()<<" The Element is deleted";
				getch();
				break;
			
			case '3':
				cls;
				cout<<peep();
				getch();
				break;
/*since the part is not working i commented it
			case '4':
				cls;
				cout<<"Enter any no: "; cin>>data;
				Nodeptr temp;
				temp=search(data);
				if(temp!=NULL) cout<<temp->info<<" is found !!";
				else cout<<data<<" is not found !!";
				getch();
				break;
*/
			case '5':
				cls;
				display();
				getch();
				break;
			
			case 27:
			return;
		};
	}
}

I don't have a lot of experience with templates but based on your other function declarations/definitions, which presumably work, have you tried something like this:

template <class Dtype>
Nodeptr Stack<Dtype>::search(Dtype item)

for the first line of the definition of search()?
