“PLEASE USE C++ IDE” 1. construct a program that will utilize the first two (2)operations of Linked List mentioned above. Your program must dothe following: 1. It must be a menu-driven program with the following choices:[A] Add Pet Name[B] Display Pet Name[C] Reverse Display[D] Delete[E] Exit SAMPLE OUTPUT: MENU[A] Add Pet Name[B] Display Pet NameIC] Reverse Display[D Delete[E] ExitEnter choice: 2. For option [A], the data that the user should add in the linkedlist are Pet Names. You have an option to use a string or achar data type. No whitespaces are needed since only one wordis used for the pet names. The program will continuously askthe user to enter pet names until letter “X” is entered.

C++ 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.
struct node{ int a; struct node * nextptr; }; Write two functions. One for inserting new values to a link list that uses the given node structure. void insert(struct node **head, int value); Second function is called to count the number of even numbers in the link list. It returns an integer that represents the number of even numbers. int countEvenNumbers(struct node *head); Write a C program that reads a number of integers from the user and insert those integers into a link list (use insert function). Later pass the head pointer of this link list to a function called countEvenNumbers. This function counts and returns the number of even numbers in the list. The returned value will be printed on the screen. Note 1: Do not modify the function prototypes.
