Question

Hi everyone trying to translate an older C program that uses array of structures into C++ program that uses linked lists. I’m a total C++ newb and I’m a little confused on the syntax of setting up a linked list in C++…. here’s my code:

#include <iostream> 
#include <stdlib.h>
#include <string>
#include <ctype.h>
#include <fstream>

using namespace std;


struct Video { 
char video_name[1024];      
int ranking;                // Number of viewer hits
char url[1024];             // Video URL
struct Video *next;  // pointer to Video structure
} 


struct Video* Collection = new struct Video;
Collection *head = NULL;                    // EMPTY linked list

In my old program Collection was an array of Video. How can I make Collection be a linkedlist of Video nodes? I am currently getting errors saying on the last two lines code saying: expected initializer before 'Collection' and expected constructor, destructor or type conversion before '*' conversion. I know my syntax is definately wrong, but I guess I dont understand how to create a linked list of Videos inside of Collection…

The c++ answer is:

struct Video { 
    std::string video_name;     
    int ranking;                // Number of viewer hits
    std::string url;             // Video URL
} 

std::list<Video> list_of_videos
