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:
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.
(C++ Language)
Create a function that writes to a file named Inventy.txt the information of 8 items. Ask the user for the item's name, the item's quantity in storage, and the item's price and write it to the file. Create a function that reads the file and items' quantity and price to two different arrays. Create a function that computes the subtotal of each item. Implement all functions inside the main program and the computed value should be displayed with the item's name.
(python)
Write a function sum_file(f) that takes a filename f. Each line in f contains a single number. You should write to the last line in the file the sum of all the numbers written in the file.

- (IN PYTHON) Problem 1 Write a function word_count() that performs the following actions: Opens a file called “novel.txt”. You can assume that the file exists and is located in the same directory as your code file. Reads in the contents of the file, and stores it in a variable called text. Uses the split() function to obtain a list containing all of the individual words in text. For details on how to use split(), you can consult this site: https://www.w3schools.com/python/ref_string_split.asp For this question, assume that all words will be separated by spaces. Returns the number of words in the lisarrow_forward(C Language) Given a set of text files containing synonyms for different words, complete the main program to output the synonyms for a specific word. Each text file contains synonyms for the word specified in the file’s name, and the synonyms within the file are grouped according to the synonyms' first letters, separated by an '*'. The program reads a word and a letter from the user and opens the text file associated with the input word. The program then stores the contents of the text file into a two-dimensional array of char* predefined in the program. Finally the program searches the array and outputs all the synonyms that begin with the input letter, one synonym per line, or a message if no synonyms that begin with the input letter are found.arrow_forward(python) Write a function startWith(File, Let) that takes a file name and a letter. Each line in the file contains 1 word. The function should store a new file with all the words that start with letter Let.

If the user does not input any names, default file names should be used, such as input.txt and output.txt. The input files have lines which look like this: 3 Tester College; 1909 33001 The first number represents the rank; it is followed by the school name, year founded, and approximate number of students. Read the list of colleges into an array of structures. You may assume that the maximum size of a college name string is 64. The program should use either the insertion sort algorithm or the selection sort algorithm to sort the array in descending order by rank. Display any k consecutive schools requested by the user. For instance, if the user enters 12, the program displays the first 2 schools in a readable format of your choice. If the user enters 15, the program displays the first five schools, if the user enters 2 7, display 7 schools beginning with the one at index 1 (2 - 1), and so…arrow_forward

- DO NOT WRITE MAIN! Only write the function. A 50% minimum deduction will be made if main is included. No libraries or comments should be specified. (OP4) Write a function to prompt the user for the filename, open the file, and verify that it opened. If the file does not open, an error message should be printed and the user re-prompted. The function should use the string passed in for the prompt string. The function should not return until the file is open. The function prototype: void openInputFile( ifstream &, string ); ifstream& - the stream to be opened. string - the prompt to be written out to the user. Use this string when prompting the user.arrow_forwardModified Programming ). (Count vowels and consonants, file input, nested-loops, switch statement) Assume that letters A, E, I, O and U are the vowels. Write a program that reads strings from a text file, one line at a time, using a while-loop. You do the following operations within each loop: • Read one line from the input file and store it in a string; Count the number of vowels and consonants (using either while-loop or for-loop) in the file string. The while-loop will terminate when the end-of-file is reached. After the loop is finished, the program displays the total number of vowels and consonants in the text file. [A text file, named “ass4_Q6_input.txt", is provided as your testing input file.]arrow_forward(C++) Write a function definition called fillStructures that takes an input file stream reference, an integer matrix and the number of rows as parameters to the function, two complexType arrays and their corresponding size. the function should prompt the user to enter 2 integer values (be sure to validate the user’s input) and fill the matrix with random values between the two provided numbers (inclusive) and fill both complexType arrays objects with values from a file.arrow_forward
