Title
Body
When I compile this: #ifndef BTREE_H #define BTREE_H #include <QList> template <class T, int degree> class btree { public: class node { public : node(); private: node* parent; QList<T> values; QList<node*> children; }; public: btree(); void insert(const T& value); node* findLeaf(const T& value); void performInsertion(const T& value, node& place); // node* root; }; #endif // BTREE_H Implementation of findLeaf is this: template <class T, int degree> btree<T,degree>::node* btree<T,degree>::findLeaf(const T &value) { if(root == NULL) return root; } This error occurs: error: need ‘typename’ before ‘btree<T, degree>::Node’ because ‘btree<T, degree>’ is a dependent scope
