Sorted List of 1994 Gas Prices
Note: This assignment can be done either as an enhancement to the program that you wrote for
In the student sample programs for this book, you will find a text file named 1994_Weekly_Gas_Averages.txt. The file contains the average gas price for each week in the year 1994, (There are 52 lines in the file. Line 1 contains the average price for week 1, line 2 contains the average price for week 2, and so forth.) Write a program that reads the gas prices from the file, and calculates the average gas price for each month. (To get the average price for a given month, calculate the average of the average weekly prices for that month.) Then, the program should create another file that lists the names of the months, along with each month’s average gas price, sorted from lowest to highest.

- Finish this program from the code posted below! Note: There should be two files Main.py and Contact.py You will implement the edit_contact function. In the function, do the following: Ask the user to enter the name of the contact they want to edit. If the contact exists, in a loop, give them the following choices Remove one of the phone numbers from that Contact. Add a phone number to that Contact. Change that Contact's email address. Change that Contact's name (if they do this, you will have to remove the key/value pair from the dictionary and re-add it, since the key is the contact’s name. Use the dictionary's pop method for this!) Stop editing the Contact Once the user is finished making changes to the Contact, the function should return.

- File names: color_square.py, chessboard.py, test_squares.py Positions on a chess board are identified by a letter and a number. The letter identifies the column; the number identifies the row. See the image below. You will provide the functions that allow us to determine: if a chessboard square is either black or white, given its coordinates. If the row/column is valid or not for the standard chessboard For example, if we pass in “d” for the column and 4 for the row, your function that determines color should return the string: “BLACK”. If we pass in "k" for the column to your function that validates columns, that function should return the boolean False. Requirements: Your function for validating the column should be able to accept upper or lowercase strings as parameters. Your functions for validating the row should be able to accept integers or strings as parameters. Your function that determines black-or-white may assume that the input has been validated prior to us calling…arrow_forwardThe attached file USPopulation,txt contains the US population in thousands, during the years 1950 through 1990.

One common physical activity that most of these devices track is the number of steps you take each day. The steps.txt file contains the number of steps a person has taken each day for a year. There are 365 lines in the file, and each line contains the number of steps taken during a day. (The first line is the number of steps taken on January 1st, the second line is the number of steps taken on January 2nd, and so forth.) Write a program that reads the file, then displays the average number of steps taken for each month. (The data is from a year that was not a leap year, so February has 28 days.)

- Assignment 5C: Level Map Creator. There are a variety of ways that game developers store their level layouts. One simple method is to associate level elements with certain symbols, and then storing them in a 2D grid inside a text file. We will use our knowledge of 2D arrays to create a very simple Level Map Creator tool. The program should prompt the user to enter a width and height for the level. Then it should initialize a 2D array and fill every element with the "*" symbol. Afterwards, the user should be given the following options via a menu: 1. Clear Level Re-initialize the 2D array and fill every element with the "*" symbol. 2. Add Platform Prompt the user to enter a starting point and length for the horizontal platform. Replace those elements in the 2D array with the "=" symbol. If the length is longer than the number of columns (or out of bounds), notify the user that this is not possible. 3. Add Item Prompt the user to enter a column and row index. Replace that element in the…arrow_forwardModify the code below to create a "Favorite Video Game List" program that is contained in three files: Game.h Game.cpp Game_List.cpp You will need do to these things as you modify the code and put it into the three files: Create a class called "Game" (instead of "Movie") that contains 3 private variables ("title", "year", and "rating") The "year" is when the game first came out. The "rating" should be from 1 to 5 (5 being the best). Add the appropriate member functions of the class (setters and getters). Continue to use the get_title_upper() function as part of the class, Game, and in the output within the main file, Game_List.cpp. Add the Default Constructor for the class with the member functions of the class. Ignore the Destructor code for now. It's there to show you where it ends up in future code. Don't forget to add the include guard to the .h file Use the scope resolution operator correctly for each file. Don't use the "using namespace std;" for the main…arrow_forwardAssignment 5A: Multiple Frequencies. In the last assignment, we calculated the frequency of a coin flip. This required us to have two separate variables, which we used to record the number of heads and tails. Now that we know about arrays, we can track the frequency of all numbers in a randomly generated sequence. For this program, you will ask the user to provide a range of values (from 1 to that number, inclusive) and how long of a number sequence you want to generate using that number range. You will then generate and save the sequence in an array. After that, you will count the number of times each number occurs in the sequence, and print the frequency of each number. Hints: You can use multiple arrays for this assignment. One array should hold the number sequence, and another could keep track of the frequencies of each number. Sample Output #1: What's the highest number you want to generate?: 5 How Long of a number sequence do you want to generate?: 10 Okay, we'll generate 10…arrow_forward
