c2955: 'treenode' : use of class template requires template argument list the treenode class is:
template <class t> class treenode{ t data; // different data type other apps treenode<t> *left; // pointer left child treenode<t> *right; // pointer right child public: treenode(t x = 0, treenode *left = null,treenode *right = null) { data = x; this->left = left; this->right = right; }; t getdata() { return data; }; treenode<t> *getleft() { return left; }; treenode<t> *getright() { return right; }; void setdata(t x) { data = x; }; void setleft(treenode *ptr) { left = ptr; }; void setright(treenode *ptr) { right = ptr; }; template<class t> friend class tree; };
i appended code treenode class posted here question - tonyd
