Implement linked list in the following activities. 1. Create a program that will input five (5) Hotel Room Number and display all entered data. Use the function display to display all data. (filename; link_display.c) 2. Create a program that will input five (5) Hotel Rate and display all entered data. Then insert 1 Hotel Room Number at the beginning of the linked list.(Filename: link_insertbeg.c) 3. Create a program that will input five (5) Hotel Rate and display all entered data. Then insert 1 Hotel Room Number at the end of the linked list.(Filename: link_insertend.c) 4. Create a program that will input five (5) Hotel Rate and display all entered data. Then insert 1 Hotel Room Number in positon 3 of the linked list.(Filename: link_insert_nth.c) 5. Merge all the programs into one program. (Link_Merge.c) The software use: C++ or Moblie C C languages

Please,help me by providing C++ programing solution. Do not use the LinkedList class or any classes that offers list functions. Implement a LinkList in C++. Pease,implement with an ItemType class and a NodeType structThe program should read a data file,and the data file has two lines of data as follow:100, 110, 120, 130, 140, 150, 160100, 130, 160The program will first add all of the numbers from the file,then display all of them,then delete.
In CPP, Modify the arrayListType by adding a member function that keep the first element in the list as is and replace subsequent elements by the result of subtracting the element from the first element. This member function returns the first element in the list. For example, if the list L contains the elements 2,1,3,4,5,3,0 and you call the member function as in L.differentiate (); The list content will then be changed to 2,1,-1,-2, -3,-1,2 And the function returns 2. The list should not be empty.
