    Syntax problems with Class Template

    I can't seem to resolve a syntax error, that is only occuring when I use a template with a pointer. Its just a basic linked list, here is the first part of my header file:

    Code:
     #ifndef LISTTEMP_H
    #define LISTTEMP_H
    #include <iostream>
    
    template <class type>
        class listtemp{
    	public:
    		const listtemp <type>& operator= (const listtemp<type>&);
    		void initializelist();
    		bool islistempty();
    		bool islistfull();
    		void print();
    		int length();
    		void destroylist ();
    		void retrievefirst(type& firstelement);
            
    		
    		listtemp();
    		
    		listtemp(const listtemp <type>& otherlist);
    		
    		~listtemp();
    		
    	protected:
    	    nodetype<type> *first;                        //line 25
    	    nodetype<type> *last;
    		
    		
    };
    
        template <class type>
        bool listtemp<type>::islistempty(){
            return (first == null);
        }
        
        template <class type>
        bool listtemp<type>::islistfull(){
            return false;
        }
    
    template <class type>
        listtemp<type>::listtemp(){
            first = NULL;
            last = NULL;
        }
        
        template <class type> 
        void listtemp<type>::destroylist(){
            nodetype<type> *temp;                          //line 49
        }
    and the error message I am getting is as follows:


    Compiler: Default compiler
    Building Makefile: "E:\C++Programs\Makefile.win"
    Finding dependencies for file: E:\C++Programs\Sortedlistmain.cpp
    Executing make...

    In file included from sortlist.h:3,
    from Sortedlistmain.cpp:3:
    listtemp.h:25: error: syntax error before `*' token
    listtemp.h:26: error: syntax error before `*' token
    listtemp.h: In member function `void listtemp<type>::destroylist()':
    listtemp.h:49: error: syntax error before `>' token



    I have checked multiple references allready, and my code syntax looks the same, so I'm guessing it may be compiler related, however I am not sure. Any help is greatly appreciated.

    Well, I'll buy into the compiler bug if you can show me where nodetype is declared.
    My best code is written with the delete key.

    Doh!

    Well, that got rid of a lot of problems, thank you, guess I need to spend more time reading my book, and not trying to jump ahead.

    Books are for weenies. You learn more by trial and error...and error, and error, and error.
