Language: C++ Create a class called publication that stores the title (char array) and price (float) of a publication. From this class derive two classes: book, which adds a page count (int) and tape, which adds a playing time in minutes (float). Each of the three classes should have a getdata() function to get its data from the user using input from the keyboard and a putdata() function to display the data.Write a main function that creates an array of pointers to publication. In a loop, ask the user for data about a particular type of book or tape to hold data. Put the pointer to the object in the array. When the user has finished entering data for all the books and tapes, display the resulting data for all the books and tapes entered, using a for loop and a single statement such as: pubarr[j] -> putdata(); To display the data from each object in the array.

C++ and the focus is on Pass by Reference: The following steps are essentially under the same problem but in order to complete a step, the previous must be completed first. For example, Step #3 cannot be completed unless Step #1 has been conducted. Step #1: Create a function to output the values of an integer array. You will have two parameters: the array and the number of elements to display. Step #2: Create an array of integers of 100 elements. File the array with the values 1 to 100 Step #3: Call the function in step 1 to print 6 elements starting at element 0 Step #4) Call the function in step 1 to print 6 elements starting at element 12. Step #5) Write a swap function that will swap two integer parameters that are passed in by reference. Step #6) Use the swap function to swap the elements in the 100 element array at element 0 and 5. Display the first 8 elements in the array (using the function in step 1)
