Answer each question given this definition of a linked list.  Assume the list has already been constructed and contains at least one 0. struct ListNode {  // a data type    double value;    ListNode *next; }; ListNode *head; Write C++ statements to output a count of how many times the number 0 occurs in the list.  If the list contains the values {1.2, 3.2, 0, 7.8, 0, 5, 0} it should output 3 because 0 occurs 3 times in the list.

Question

Answer each question given this definition of a linked list.  Assume the list has already been constructed and contains at least one 0.

struct ListNode {  // a data type
   double value;
   ListNode *next;
};
ListNode *head;

  1. Write C++ statements to output a count of how many times the number 0 occurs in the list.  If the list contains the values {1.2, 3.2, 0, 7.8, 0, 5, 0} it should output 3 because 0 occurs 3 times in the list.
  2. Write C++ statements to declare a pointer p of type ListNode * and make it point to the node BEFORE the first 0 in the list.  If the list contains the values {1.2, 3.2, 0, 7.8, 0, 5, 0}, p should point to the 3.2.  Your code should work for any list that contains a 0.  You may assume the first value is NOT a 0.
  3. Remove the node containing the first 0 in the list (and deallocate it).  Assume p is of type ListNode * and is already pointing to the node BEFORE the first 0, and that the first value in the list is NOT a 0.
