void List::push_back(Node* p) { if(lastNode == nullptr) { firstNode = p; lastNode = p; } else { lastNode->setNextNode(p); lastNode = p; } Node* List::pop_back() { Node* saveLast = nullptr; if( numberOfNodes == 0 ) { return nullptr; } else if(numberOfNodes == 1) { saveLast = lastNode; lastNode->setNextNode(NULL); numberOfNodes--; return saveLast; } else { saveLast = lastNode; lastNode->setNextNode(NULL); numberOfNodes--; return saveLast; } } numberOfNodes++; } int main() { node stack; stack.push(5); stack.push(7); stack.push(9); stack.push(10); stack.push(1); stack.pop(); stack.print(); return 0; }
