[prog] C++ Templates

All this looks okay to me.

>template <typename T>
>Ordlist<T size> : count(size)

I think what you want here is:
   template <typename T>
   Ordlist<T>::Ordlist(int size) : count(size){
   }

The "::" indicates membership. The ":" (which is used only in a 
constructor) is used to call the constructors of class members. This is 
frivolous in this case (you're calling the "constructor" of an int), but 
when you're dealing with complex classes it can be useful.

>        info = new T[size * sizeof(T)];

You don't have to multiply by sizeof(T) here: new T[n] allocates n T's, not 
n bytes.

>template <typename T>
>int insert(T item)

You want:
   template <typename T>
   Ordlist<T>::insert(T item)


>template <>
>int isfull(void)

Nothing in C++ would surprise me, so the above might somehow compile under 
some circumstances, but it's not what you want. You want:
   template <typename T>
   Ordlist<T>::isfull(void)

>void display ( void)

This should be declared similarly to the above methods.
