Class inheritance format question?

[Outlaw782]

I am trying to figure out how to link my function prototype to my actual function using templates. I am very confused on how to do this correctly. Could anyone please help?

prototype:

template <class T>

class OListType:ListType<T>{

private:
	void insert_item(const T&);
};

Function definition

  template <class T>
  T OListType<T>::insert_item(const T&)

External linking doesn't work well with templates. What you have here looks fine as long as you put the definition of insert_item in the header file. You also need to use the same return type in both places.

void insert_item(const T&);
T OListType<T>::insert_item(const T&)
