For example if user1 Selects a small pizza with the toppings, tomato and pepperoni and a crust type of thin crust. And user2 selects a medium pizza, with toppings, extra cheese and green peppers and a medium crust. How would I place these two orders into an Array List and then print them using the "Print All Orders"?Scores Class Write a class named Scores which should have the following attribute: • _scores (a list to hold test scores, 0 - 100. Initially empty. ) The Scores class should have an _init__ method that creates the _scores attribute. It should also have the following methods: • add_score: this method adds a score to the __scores list. It accepts a single score as it's' only argument. • get_average: this method accepts no arguments. If _scores is empty, this method returns -1. Otherwise, it returns the average of all scores in _scores. • get_high_score: this method accepts no arguments. if scores is empty, this method returns -1. Otherwise, it returns the highest score in __scores. • get_low_score: this method accepts no arguments. if scores is empty, this method returns -1. Otherwise, it returns the lowest score in scores. • _str_: This method returns a string similar to the following (assuming the _scores contains 89, 77, 93): Once you have written the class, write a program that…#ifndef lab5ExF_h #define lab5ExF_h typedef struct point { char label[10]; double x ; // x coordinate for point in a Cartesian coordinate system double y; // y coordinate for point in a Cartesian coordinate system double z; // z coordinate for point in a Cartesian coordinate system }Point; void reverse (Point *a, int n); /* REQUIRES: Elements a[0] ... a[n-2], a[n-1] exists. * PROMISES: places the existing Point objects in array a, in reverse order. * The new a[0] value is the old a[n-1] value, the new a[1] is the * old a[n-2], etc. */ int search(const Point* struct_array, const char* target, int n); /* REQUIRES: Elements struct-array[0] ... struct_array[n-2], struct_array[n-1] * exists. target points to string to be searched for. * PROMISES: returns the index of the element in the array that contains an * instance of point with a matching label.

- Searching - a user should be able to search by ID or by item name create only one menu item for searching a user should be able to enter the name of the item using any case, (for example, sTRolleR) you may wish to store items in all lower/upper case to expedite the search write one search function that can search by ID and name and goes through the array of structs/objects only once show the entire record if found or an appropriate message if not Sorting - sort by any field write one function to sort by any field using a parallel array of pointers use Bubble Sort is not the most effective but the easiest to modify. do not copy and paste sort code five times into the same function. sorting using pointers is faster because you have to swap pointers only, which are normally stored in 4 bytes each; it also allows you to preserve the original order of the items If you choose to have a submenu, a submenu must have an option to go back to the previous menu or main menu if a user got…Parameter: An array of strings.
