Assignment help 98

So essentially I’m trying to understand how a C++ listnode can link a list class with three member functions 1st [void add (double x)]; 2nd [boolean ismember (double x)]. While this last member function 3rd [int search (double x)] returns the position of a number x on a list. The link list class should also have a default constructor such as LinkedList(). The first node in the list is at position 0, the second node is at position 1, and so on. If x is not found on the list, the search should return -1. I’m trying to understand this in the form of a C++ driver program.
