In this part your will have questions about C++ functions with pointers. • Write a function that takes three integer pointer as parameters and calculates sum of all numbers. This function must return the result as a pointer. • Declare a structure about a book which has properties such as name and price etc. Then create a list of book with 5 books. After that define a function that takes this book-list as a pointer and print out list items. • Write a function that calculates total price of the book in the book list (note: take the book-list as a pointer again). Write all function prototypes and test all functions within a single main functions.
