Write a program that reads movie data from a CSV (comma separated values) file and output the data in a formatted table. The program first reads the name of the CSV file from the user. The program then reads the CSV file and outputs the contents according to the following requirements in c++ : Each row contains the title, rating, and all showtimes of a unique movie. A space is placed before and after each vertical separator ('|') in each row. Column 1 displays the movie titles and is left justified with a minimum of 44 characters. If the movie title has more than 44 characters, output the first 44 characters only. Column 2 displays the movie ratings and is right justified with a minimum of 5 characters. Column 3 displays all the showtimes of the same movie, separated by a space. Each row of the CSV file contains the showtime, title, and rating of a movie. Assume data of the same movie are grouped in consecutive rows. Hints: Use the find() function to find the index of a comma in each row of the text file. Use the substr() function to extract texts separated by the commas. Ex: If the input of the program is: movies.csv and the contents of movies.csv are: 16:40,Wonders of the World,G 20:00,Wonders of the World,G 19:00,Journey to Space ,PG-13 12:45,Buffalo Bill And The Indians or Sitting Bull's History Lesson,PG 15:00,Buffalo Bill And The Indians or Sitting Bull's History Lesson,PG 19:30,Buffalo Bill And The Indians or Sitting Bull's History Lesson,PG 10:00,Adventure of Lewis and Clark,PG-13 14:30,Adventure of Lewis and Clark,PG-13 19:00,Halloween,R the output of the program is: Wonders of the World | G | 16:40 20:00 Journey to Space | PG-13 | 19:00 Buffalo Bill And The Indians or Sitting Bull | PG | 12:45 15:00 19:30 Adventure of Lewis and Clark | PG-13 | 10:00 14:30 Halloween | R | 19:00
Write a program that reads movie data from a CSV (comma separated values) file and output the data in a formatted table. The program first reads the name of the CSV file from the user. The program then reads the CSV file and outputs the contents according to the following requirements in c++ :
- Each row contains the title, rating, and all showtimes of a unique movie.
- A space is placed before and after each vertical separator ('|') in each row.
- Column 1 displays the movie titles and is left justified with a minimum of 44 characters.
- If the movie title has more than 44 characters, output the first 44 characters only.
- Column 2 displays the movie ratings and is right justified with a minimum of 5 characters.
- Column 3 displays all the showtimes of the same movie, separated by a space.
Each row of the CSV file contains the showtime, title, and rating of a movie. Assume data of the same movie are grouped in consecutive rows.
Hints: Use the find() function to find the index of a comma in each row of the text file. Use the substr() function to extract texts separated by the commas.
Ex: If the input of the program is:
movies.csv
and the contents of movies.csv are:
16:40,Wonders of the World,G 20:00,Wonders of the World,G 19:00,Journey to Space ,PG-13 12:45,Buffalo Bill And The Indians or Sitting Bull's History Lesson,PG 15:00,Buffalo Bill And The Indians or Sitting Bull's History Lesson,PG 19:30,Buffalo Bill And The Indians or Sitting Bull's History Lesson,PG 10:00,Adventure of Lewis and Clark,PG-13 14:30,Adventure of Lewis and Clark,PG-13 19:00,Halloween,R
the output of the program is:
Wonders of the World | G | 16:40 20:00 Journey to Space | PG-13 | 19:00 Buffalo Bill And The Indians or Sitting Bull | PG | 12:45 15:00 19:30 Adventure of Lewis and Clark | PG-13 | 10:00 14:30 Halloween | R | 19:00
#include <iostream>
#include <cstring>
#include <iomanip>
#include <fstream>
using namespace std;
int main() {
/* Type your code here. */
return 0;
}
I've taken the user's input in this case and stored it in a variable.
I then opened the CSV file and copied the contents into a dictionary, where the showtime list is the value and the key is the combination of the movie title and rating separated by a comma.
I then looped through the dictionary to get its values.
In response to the inquiry, I have finally printed the extracted values as a table.
import csv
# user input
filename = input("Enter the CSV file name: ")
movies_dict = {}
with open(filename,'r') as file: #opening the file
reader = csv.reader(file)
for row in reader: #reading the content
key = row[1] +','+ row[2]
tempList=[]
if key in movies_dict: #checking and stroing in form of dictionary
tempList = movies_dict[key]
tempList.append(row[0])
movies_dict[key] = tempList
# looping over the dictionary and printinng the data
for key,value in movies_dict.items():
# extarcting the values
tempList = key.split(',')
movieName = tempList[0]
movieRating = tempList[1]
# if the movie title is greater than 44 then snipping it
if len(movieName) > 44:
movieName = movieName[:44]
print(movieName.ljust(44),end=" | ")
print(movieRating.rjust(5),end=" | ")
for time in value:
print(time,end=" ")
print()
