Request For Member In Something Not A Structure Or Union

just like you, helping each other. Join them; it only takes a minute: Sign up “Request for member which is of non-class type”, assignment statement incorrect? up vote 2 down vote favorite I'm trying to cycle through http://stackoverflow.com/questions/16364116/request-for-member-which-is-of-non-class-type the data contained in each node in a list called _snakeSegments. (note: classes have been written by myself and are not part of STL ect). Each data element is a Sprite that represents a single segment of my snake. I'm getting the following error when i try to compile: request for member 'GetPrev' in 'currentNode', which is of non-class type 'Node*'. The compiled has flagged the line where i try to assign the next http://stackoverflow.com/questions/9966295/request-for-member-which-is-of-non-class-type-assignment-statement-incorrect currentNode in the for loop below: void Snake::Draw(prg::Canvas& c) { Node* currentNode = _snakeSegments.GetHead(); for (int i=0; i < _snakeSegments.NumberOfNodes(); ++i){ currentNode->GetData().Draw(c); currentNode = currentNode.GetPrev(); //compiler shows error here } } Heres the definition of GetPrev. Which, when called upon a node, returns a node pointer to the previous node.. template Node* Node::GetPrev() { return _prev; } Um well i'm a little confused and would appreciate any help! Please ask if you need more information/ i'm being unclear, thanks. c++ templates pointers share|improve this question edited Apr 1 '12 at 17:11 indiv 10.6k43269 asked Apr 1 '12 at 16:59 Holly 97032852 Sorry i'm a fool! Just not thinking straight cheers all –Holly Apr 1 '12 at 17:09 add a comment| 3 Answers 3 active oldest votes up vote 4 down vote accepted currentNode is a pointer, which means you need to access its attributes via `->, like you did on the line above: currentNode->GetPrev() You should really try to learn to differentiate between pointers and instances. Pointer attributes are always referred to via ->. share|improve this answer answered Apr 1 '12 at 17:01 Boris Strandjev 27.5k66190 add a comment| up vote 4 down vote If currentNode is a pointer, then you access member functions with -> instead of ., just like you do for member variables. sh
