intList SpecificationsS You are required to come up with a separate implementation file (IntList.cpp) that implements the member functions of the IntList class. While developing your IntList class you may write your own test harness (within a file named main.cpp) but I provide the main.cpp that is used for testing output on zyBooks. Never implement more than 1 or 2 member functions without fulling testing them with your own test harness. IntNode struct and IntList header To simplify this project, I am providing the header file. Please see the discussion board post to obtain the file. It contains the IntNode code that you must use. You are not allowed to alter this header file in any way whatsoever. IntList class You should define function stubs for all class functions to allow the program to fully compile. Recall function stubs do not have logic mplemented they are simple empty functions or functions with only a return statement that are implemented to allow compilation and execution. Encapsulated (Private) Data Fields • head: IntNode * tail: IntNode * Public Interface (Public Member Functions) IntList(): Initializes an empty list. ~IntList(): Deallocates all remaining dynamically allocated memory (all remaining IntNodes). • void display) const: Displays to a single line all of the int values stored in the list, each separated by a space. This function does NOT output a newline or space at the end. • void push_front(int value): Inserts a data value (within a new node) at the front end of the list. void pop_front(): Removes the value (actually removes the node that contains the value) at the front end of the list. Does nothing if the list is already empty. • bool empty() const: Returns true if the list does not store any data values (does not have any nodes), otherwise returns false. • void push_back(int value): Inserts a data value (within a new node) at the back end of the list.
Need to use those main.cpp and IntList.h
