Modify the C program from project 9(which split dealer.c into three source files and two header files which can be found below in the pictures) by adding and modifying the following functions:

1) Add a delete function in car.c that deletes a car from the list. The function should delete a player by the cars make, model, color, and manufacture year. This information will be entered by the user. The function should have the following prototype:

struct car* delete_from_list(struct car *list);

-You will also need to add the function prototype to the header file; modify the main function in dealer.c to add d for delete option in the menu and it calls the delete function when the d option is selected.

2.) Modify the append_to_list function so the car is inserted into an ordered list (by make, then model) and the list remains ordered after the insertion. For example, ford escape should be before ford taurus in the list; ford taurus should be before jeep wrangler in the list; if the make and model are the same, the car entries do not need to be ordered by other members.
