Question

Write this program in C language

Ensure the program output is exactly as described, and that the whitespace of your source code is well formatted. Utilise good naming practices when declaring variables. EXERCISE NAME: Recursive Movie In the history of Jurassic Park movies the following movies were released: Movie's Name: Jurassic Park The Lost World: Jurassic Park Jurassic Park III Jurassic World Year of Release: Rotten Tomatoes: 1993 93% 1997 51% 2001 50% 2015 72% Implement a structure type named Movie. Use appropriate data types and names for the structure's members. Add a member to the movie structure which represents whether the movie has a sequel, or not; this member should be a pointer to a struct Movie In the main function instantiate four structure variables, one for each movie listed in the table above. For this exercises, ensure each Movie structure variable is stored on the heap. Set the members of each structure appropriately. Next, create a function named print_movie, which can be passed a single struct Movie variable by reference. Declare a prototype for this function. Use function recursion to print out a movie's details, and its sequels, if it has any. When the Jurassic Park structure variable reference is passed to the print_movie function the following output must be generated: Name : Jurassic Park Year of Release: 1993 Rotten Tomatoes: 93% Jurassic Park's sequel was... Name: The Lost World: Jurassic Park Year of Release: 1997 Rotten Tomatoes: 51% The Lost World: Jurassic Park's sequel was... Name: Jurassic Park III Year of Release: 2001 Rotten Tomatoes: 50% Jurassic Park III's sequel was... Name: Jurassic World Year of Release: 2015 Rotten Tomatoes: 72% Jurassic World has no sequel, yet!

Answer 1

Your given problem can be easily solved by implementing singly linked list concept, i have written the code for using the same concept.

The code is written with well inline docs. and screenshots are also attached , kindly follow them for better uderstanding.

#include<stdio.h>

    int rotten_tomatoes_rating;

    // pointer member to represent sequel

    struct Movie *has_sequel;

        printf("%s's sequel was....\n\n",movie->name);

        // calling print_movie recurrsively to print all the sequels

        print_movie(movie->has_sequel);
