4.- What to do for Part 1 Your task for part 1 can be summarized as implementing the compound data structures that will allow you to build a linked list of movie reviews a) 15 marks) Implement the compound data type that stores one movie review. This compound type will be called 'Movie Review and will contain the following fields: movie_title movie_studio year BO_total Score cast - A string with length 1024 - A string with length 1024 - An int in 1920-2999 - the Box Office total) A double floating point value - For part 1 this is just an int in 0-100 (like Rotten Tomatoes scores!) - A pointer to a linked list of cast members who were in the movie (there is an associated data type for this called Castlist, you'll implement that at the end!). Make sure you have the correct types, and the correct lengths for strings, as well as the correct names for the fields - otherwise your code won't pass the tests. b) (5 marks) Implement the compound data type required to hold a linked list node with one movie review. The type must be called 'ReviewNode' and must contain: review next - A Movie Review' variable containing information for one movie - The pointer to the next node in the list 15 marks) Implement the new Movie ReviewNodeftitle, stadio, year, BO total, score) function. This "function allocates and initializes a new movie review. Your function must return the pointer to the newly allocated, initialized node. d) 110 marks Implement the function insert Movie Review (titleshdi, year, total score, head. This function: - Takes as input the information for a movie review. - Takes as input the current head of the linked list of reviews - Checks that the requested movie is not already in the linked list (uf it is in the list prints "Sorry, that movie already exists and returns the current list head pointer -Obtains a new linked-list node, and fills in the movie information - Inserts the new node at the head of the linked list. - Returns a pointer to the new head node. 4.- What to do for Part 1 Your task for part 1 can be summarized as implementing the compound data structures that will allow you to build a linked list of movie reviews a) 15 marks) Implement the compound data type that stores one movie review.
