Question

Need help with this C++ assignment, please use comments so I can better understand your code like comments above your function header explaining what the function does and the purpose of each variable. etc.

Assignment:

Write a C++ program that reads a text file containing a list of movies "Movie_entries.txt" . Each line in the file contains tile, director, genre, year released and running time of a specific movie. Each field is separated by comma. Print out movie titles sorted alphabetically.

Detailed specifications:

1. File processing:
   • Program should try to open a file using a default file path first, then check if it was successful, if not, ask the user for a different file name/path and try again until it succeeds. Do not try to process a file that you could not open. Remember to close the file when done reading.
   • Read each line from the file using getline: getline (ifstream input, string line)
2. Store the movie titles in a vector (not an array!).
   • To separate the title from the line, you can make the line a stream:
     • stringstream lineStream(line);
     • then use getline again to take the title: getline(lineStream, title, ',');
   • To add values to a vector, use function push_back.
3. Sort the data using the sort function (you will need this for the median)
   • Refer to http://www.cplusplus.com/reference/algorithm/sort/ (Links to an external site.)Links to an external site. to learn how to use sort.
4. Define a separate function to print the required info on the screen:
   • This function should receive the vector as a parameter.
   • Use a range-based for loop to print the titles.
5. Do not use global variables! Do not use goto!

#include<vector>    //for vector
#include<algorithm> //for sort
#include<fstream>   //for ifstream

using namespace std;

    ifstream fin;   //file pointer

    string line,title; //strings for line and movie title
