Question
Help make a C++ program that:
1. Queries the user for the name of a file of text.
2. Opens the file, and maintains two lists: one list for words beginning with the letter
"D" or "d", and a second list for words beginning with any other letter. Each list
must maintain words in alphabetical order.
3. Each node in the list must contain the word and the number of times that the word appears.
4. Display (a screen at a time) each of the lists showing the alphabetized list of words and the
number of times that each appears.
Please have the main function as the first function in the program

- Please follow the instructions The function first_words in python takes one parameter, fname, the name of a text file, and returns a list containing the first word from each line of the file. For example, if the file contents are: apples are red bananas are yellow limes are green then the list ["apples", "bananas", "limes"] should be returned.NOTE: You may assume the file will contain no blank lines.BIG HINT: If line is a string representing a line of text (inside of a for loop!), then L = line.split() creates a list of the words in the line. For example: Test Result L = first_words("snakes.txt") print(L) ['Cottonmouth', 'Timber', 'Black', 'Tiger', 'Copperhead', 'Eastern', 'Western', 'Eastern', 'Prairie', 'Mojave']arrow_forwardin PYTHON Write a function that accepts a list as an argument and calculates the sum of each elementof the list.arrow_forwardThe for statement defines a list-iterating loop.

- Im Python pleasearrow_forwardWhat are the steps for making a list?arrow_forwardLottery number generator: Write a program that generates aseven-digit lottery number. The program should have a loopto generate seven random numbers, each in the range 0through 9 and assign each number to a list element.2. Write another loop to display the contents of the list.3. Tip: You will need to create/initialize your list before you canassign numbers to it.4. Use program 7-1 sales_list as an example. You will start witha seven-digit lottery number that contains all zeros. Then inyour loop, you will assign a random number instead ofgetting the data from the user.Turn in your program to the practice assignment link in coursecontent.arrow_forward
- python LAB: Subtracting list elements from max When analyzing data sets, such as data for human heights or for human weights, a common step is to adjust the data. This can be done by normalizing to values between 0 and 1, or throwing away outliers. Write a program that adjusts a list of values by subtracting each value from the maximum value in the list. The input begins with an integer indicating the number of integers that follow.arrow_forwardParallel Lists JumpinJive.py >- Terminal Summary 1 # JumpinJava.py - This program looks up and prints t and prices of coffee orders. 2 # Input: In this lab, you use what you have learned about parallel lists to complete a partially completed Interactive Python program. 3 # Output: Name and price of coffee orders or error if add-in is not found 4 The program should either print the name and price for a coffee add-in from the Jumpin' Jive 5 # Declare variables. Coffee Shop or it should print the message "Sorry, we do not carry that.". 6 NUM_ITEMS = 5 # Named constant 8 # Initialized list of add-ins 9 addIns = ["Cream", "Cinnamon", "Chocolate", "Amarett "Whiskey"] Read the problem description carefully before you begin. The data file provided for this lab includes the necessary input statements. You need to write the part of the program that searches for the name of the coffee add-in(s) and either prints the name and price of the add-in or prints 10 the error message if the add-in is not…arrow_forwardQUESTION 4 in phython language Write a program that creates a list of N elements (Hint: use append() function), swaps the first and the last element and prints the list on the screen. N should be a dynamic number entered by the user. Sample output: How many numbers would you like to enter?: 5 Enter a number: 34 Enter a number: 67 Enter a number: 23 Enter a number: 90 Enter a number: 12 The list is: [12, 67,23, 90, 34]arrow_forward
