nullptr. In the program below, free the memory allocated by the linked list.

- Assume a linked list contains following integers: 5, 2, 4, 6, 8, 3, 15 and the pointer head is pointing to the first node of the list. What will be the value of variable a after the following statements are executed: Node<int> *curNode=head; int a=0; while(curNode!=NULL){ a+=curNode->getItem(); curNode=curNode->getNext(); if(curNode!=NULL) curNode=curNode->getNext(); } A.32 B.43 C.19 D.18arrow_forwardAnybody??arrow_forwardC++ The List class represents a linked list of dynamically allocated elements. The list has only one member variable head which is a pointer that leads to the first element. See the following code for the destructor to List. ~ List () { for (int i = 0; i <size (); i ++) { pop_back (); } } What problems does the destructor have? Select one or more options: 1. There are no parameters for the destructor. 2. The return value from pop_back (if any) is nerver handled. 3. The destructor will create a stack overflow. 4. The destructor will create dangling pointers. 5.The destructor will create memory leaks. 6.The destructor will create undefined behavior (equivalent to zero pointer exception). 7.The condition must be: i <size () - 1 8. There is at least one problem with the destructor, but none of the above.arrow_forward
