sure you've probably run across it too... If so, I'd appreciate some help! I've been coming close to banging my head against the table for the last hour or so trying to figure out why I'm getting this error. Again. I'd really appreciate some help figuring out why I'm getting this error: "request for member 'measureIMU/readIMU' in 'vector', which is of request for member which is of non-class type struct non-class type 'IMU () ()'".ino:Code: [Select]

Please excuse me, I have just entered into C++ and was starting up with DS. STACK!!! My code: I think using namespace std; typedef char stackElement; class Stack { public: stackElement *contents; //dynamically allocated: as we do not know what would be the size of our array. int top, maxSize; // current Top index in the array //max size http://stackoverflow.com/questions/8547486/error-request-for-member-in-this-which-is-of-non-class-type-const of the array; we need it to know if the array is full Stack(int maxSize) { contents = new stackElement(maxSize); this.maxSize = maxSize; if(contents == NULL) { cout<<"Insufficient memory"; exit(1); } top = -1; } ~Stack() { delete [] contents; contents = NULL; maxSize = 0; top = -1; } bool isEmpty()const { return top < 0; } bool isFull() const { return top == maxSize - 1; } void push(stackElement element) { if(isFull()) { cout<<"STACK IS ALREADY FULL"; exit(1); } top = top + 1; contents[top] = element; } }; int main() { cout<<"STACK IMPLEMENTATION"; int i = 1; Stack s1(i); s1.push('a'); s1.push('1'); return 0; } I am getting this error: error: request for member 'maxSize' in 'this', which is of non-class type 'Stack* const' c++ share|improve this question edited Dec 17 '11 at 19:52 ziesemer 20.2k34971 asked Dec 17 '11 at 19:49 Roger 3831315 3 You're ignoring the rule of three. Hint 1: What happens if you copy-construct a Stack? Hint 2: Shallow pointer copies. –Xeo Dec 17 '11 at 19:56 add a comment| 3 Answers 3 active oldest votes up vote 12 down vote accepted If at all, you'd have to write this->maxSize = maxSize;, since this is a pointer. But better not to write
