C++:

Use a linked list to store your favorite movies.

Store the movie objects into a linked list, display the movie information by sorting with the title, viewed year, and rating.

You may need three more functions to display the sorted movie information by passing the pointer of the first movie object in the linked list:

I have already figured out most of the code, but I am having trouble fixing the bottom list "**Display Movies info sorted by viewed years**" to output correctly

Here is my code:

-------------------------

#include

#include

using namespace std;

struct movie

{

string title;

int viewed_year;

int rating;

movie* next;

};

void list_movie(const movie* head)

{

cout

cout

int i = 1;

for (const movie* p = head; p; p = p->next)

{

cout

cout title;

cout viewed_year;

cout rating

}

}

void arrange_by_title(movie* &head)

{

movie* temp = head->next;

if (head->title.compare(head->next->title) > 0)

{

head->next = temp->next;

temp->next = head;

head = temp;

}

temp = head->next;

if (head->title.compare(temp->next->title) > 0)

{

temp->next->next = head;

head = temp->next;

temp->next = NULL;

}

else

{

head->next = temp->next;

head->next->next = temp;

temp->next = NULL;

}

}

void arrange_by_rating(movie* &head)

{

movie* temp = head->next;

if (head->rating > head->next->rating)

{

head->next = temp->next;

temp->next = head;

head = temp;

}

temp = head->next;

if (head->rating > temp->next->rating)

{

temp->next->next = head;

head = temp->next;

temp->next = NULL;

}

else

{

head->next = temp->next;

head->next->next = temp;

temp->next = NULL;

}

}

void arrange_by_viewed(movie* &head)

{

movie* temp = head->next;

if (head->viewed_year > head->next->viewed_year)

{

head->next = temp->next;

temp->next = head;

head = temp;

}

temp = head->next;

if (temp->next->viewed_year viewed_year)

{

temp->next->next = head;

head = temp->next;

temp->next = NULL;

}

else

{

head->next = temp->next;

head->next->next = temp;

temp->next = NULL;

}

}

int main()

{

movie* firstmovie = 0;

string title1, title2, title3; //3 Strings to store names of the movies

int viewed_year1, viewed_year2, viewed_year3; //3 ints's to store viewed year of the movies

int rating1, rating2, rating3; //3 ints's to store rating of the movies

cout

getline(cin, title1);

cout

cin >> viewed_year1;

cout

cin >> rating1;

cin.get();

cout

getline(cin, title2);

cout

cin >> viewed_year2;

cout

cin >> rating2;

cin.get();

cout

getline(cin, title3);

cout

cin >> viewed_year3;

cout

cin >> rating3;

// 3 movie objects to store the movies

movie a = { title1, viewed_year1, rating1 };

movie b = { title2, viewed_year2, rating2 };

movie c = { title3, viewed_year3, rating3 };

a.next = firstmovie;

firstmovie = &a;

b.next = firstmovie;

firstmovie = &b;

c.next = firstmovie;

firstmovie = &c;

// Function call to print the movies

// list_movie(firstmovie);

cout

arrange_by_title(firstmovie);

list_movie(firstmovie);

cout

arrange_by_rating(firstmovie);

list_movie(firstmovie);

cout

arrange_by_viewed(firstmovie);

list_movie(firstmovie);

}

I know the issue somewhere under my "void arrange_by_viewed(movie* &head)" function, but still having no luck. Any help is greatly appreciated, thank you.
