please i want the solution using C++ and beside each code please write a comment so I can easily understand the code

1. Create a new project called Lab4_ Link List Project2. 2. Create a Node class & a LinkedList class, and program the tasks in the main method. 3. Taskl: Write and test a method named swapFirstLast() which swaps the data of first and last nodes in the linked list. Note: If list is empty or contains only one node, your code should display error message accordingly. Hint: Use following method header: void swapFirstLast() { } 4. Task2: Write and test a method named countEvenOddNodes() which counts and displays number of even nodes as well as number of an odd nodes present in the linked list. Note: If list is empty, your code should display error message accordingly. Hint: Use following method header: void count EvenoddNodes () { int evenNodes = 0; int oddNodes = 0; cout Task4: deleteNodeAfter () "; //you will complete code here 8. When you run this program, it will display the following screen: Sample run 1: If the list is empty. How many values do you want to insert: 0 Printing All Nodes: The list is empty countNodes() Error: cannot count nodes (the list is empty) printEvenkodes) Error: cannot print even nodes (the list is empty) Taski: swapFirstLant() Error: cannot swap(the list has less than two nodes) AAAA Task2: countEvenOddNodes) The list is empty Number of Even nodes in the list is o Number of Odd nodes in the list 13 O Taxk3: addNodeAfter) Error: cannot add node after (the list is empty) V AA Task4: deleteNodeAfter) Erroz: cannot delete node after the list is empty) Samples run 2: * If the list has one element. 1) Printing an Nodes: 12, countNodes () Number of nodes in the linked list is 1 print venkodes() Printing Even Nodes. 12, V V Taski: swapFirstLast () Error: cannot swap(the list has less than two nodes) VVV Task2: countEvenoddNodest) Number of Even nodes in the list is 1 Number of Odd nodes in the list is o V V V Task3: addNodeAfter) Please enter the node data After which you want to add a new node: 30 Error: There is no node in the List with 30 AAA Task4: deleteNodeAfter() Please Enter the node data after which you want to delete a node: 30 Error: There is no node in the List with 30 How many values do you want to insert: 1 value 1: 12 12 was successfully inserted into the list.
