(Solved) : Need Help C Program See Solutioncpp Actuall Implementation Solutionh Declare Classes Testc Q28022504 . . . .

Need help with this C++ program. See belowSolution.cpp(actuall implementation), Solution.h(declareclasses) and test.cpp(this is use for testing no need tomodify)

//Solution.cpp

#include “Solution.h”

/*

Put your actual implemetation in this file. See Solution.h fordetails.

*/

//end of Solution.cpp

//Solution.h

#pragma once

#include

typedef int ListItem;

#define INVALID_LIST_ITEM (-1)

//

// TODO !!!

//

/*

Use this header to declare your classes. Do the actual functionimplementation in Solution.cpp.

It’s not really necessary but it’s a good habit for largerprojects.

Ideally we’d put each class in its own header and source butthese should be pretty simple and short.

*/

class List

{

//

// TODO !!!

//

/*

This is the abstract class from which our list implementationswill derive.

You should add a constructor, destructor, and the followingfunctions:

unsigned int GetSize()
