Use proper formatting so that when we print 2 or more courses as rows, the same members align below each other.

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 (I) 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. Ex: If the input of the program is: movies.csv and the contents of…arrow_forward
- Write a program in C++ that prints a sorted phone list from a database of names and phone numbers. The data is contained in two files named "phoneNames.txt" and "phoneNums.txt". The files may contain up to 2000 names and phone numbers. The files have one name or one phone number per line. To save paper, only print the first 50 lines of the output. Note: The first phone number in the phone number file corresponds to the first name in the name file. The second phone number in the phone number file corresponds to the second name in the name file. etc. You will find the test files in the Asn Five.ziparrow_forwardYou are going to write a program (In Python) called BankApp to simulate a banking application.The information needed for this project are stored in a text file.

The program should create a dictionary in which the keys are the individual words found in the file and the values are the number of times each word appears. For example, if the word "the" appears 128 times, the dictionary would contain an element with 'the' as the key and 128 as the value. The program should either display the frequency of each word or create a second file containing a list of each word and it's frequency. This program has really been giving me trouble. Any help is great appreciated. Thanks so much!arrow_forward
- Implement in C Programming 9.9.1: LAB: Thesaurus 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. Hints: Use the malloc() function to allocate memory for each of the synonyms stored in the array. A string always ends with a null character ('\0'). Use ASCII values to map the row index of the array to the…arrow_forwardWrite a C++ Program using classes, functions (recursive and otherwise), arrays and other C++ commands that reads words from a file (one column only), storing them into an array. Once the array is sorted alphabetically ascending, the user is prompted to enter a word. The program reports whether or not the word was in the array of words. and its position on the array. If the word is found, the program should report the number of letters in that word.arrow_forwardWrite a program that reads a list of enrollments from a file and prints a class roster for the teacher. Make the class roster line up as neatly as you can and still fit on the screen. You can choose the actual values to use for your data. Make sure to do enough sets of data to well test your program! (Empty data set, normal data set, data with large values, data with short values, etc.) Also, your program can't know ahead of time how many people are enrolled in the class... Don't forget to read the file's name from the user and protect your program against any errors that may occur during the opening of the file. Try to use functions to break up the program into more manageable pieces. USING C++ As an example, you might have the data file contain:arrow_forward
