I want to write a class like this. How can I define findMin and findMax function in another cpp file?

template <typename Comparable>
class BinarySearchTree
{
private:
    struct BinaryNode
    {
        Comparable element;
        BinaryNode *left;
        BinaryNode *right;

        BinaryNode(const Comparable & theElement, BinaryNode *lt, BinaryNode *rt)
        : element(theElement), left(lt), right(rt){}
    };

    BinaryNode * findMin(BinaryNode *t) const;
    BinaryNode * findMax(BinaryNode *t) const;
}

That question doesn't contains the type that return type is a pointer to object I think – Tian Oct 27 '14 at 08:39
The return type is absolutely irrelevant, `BinarySearchTree` is a class template. – user657267 Oct 27 '14 at 08:40
But I can't use like this: template BinarySearchTree::BinaryNode * BinarySearchTree::findMax(BinarySearchTree::BinaryNode *t) const – Tian Oct 27 '14 at 08:43
All of the answers you seek are in the linked answer, give up, it isn't possible. – user657267 Oct 27 '14 at 08:44
