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.

World Series Winners In this chapter's source code folder (available on the Computer Science Portal at www. pearsonhighered.com/gaddis), you will find a text file named WorldSeriesWinners. txt. This file contains a chronological list of the World Series' winning teams from 1903 through 2009. The first line in the file is the name of the team that won in 1903, and the last line is the name of the team that won in 2009. (Note the World Series was not played in 1904 or 1994. There are entries in the file indicating this.) Write a program that reads this file and creates a dictionary in which the keys are the names of the teams, and each key's associated value is the number of times the team has won the World Series. The program should also create a dictionary in which the keys are the years, and each key's associated value is the name of the team that won that year. The program should prompt the user for a year in the range of 1903 through 2009. It should then display the name of the…arrow_forward
- A Personal Fitness Tracker is a wearable device that tracks your physical activity, calories burned, heart rate, sleeping patterns, and so on. 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.) You don't need to see the file , Just write a code using the "file" like this def main(): with open("steps.txt", "r") as file:arrow_forwardAn organization has a file named “staff.txt” that has 10 records of staffs having their id, name and salary. Using the concept of structure, you are required to write a program to ask the details of three more staffs and add them in the file.

For each volume, they want a label that contains the author’s name, the title of the work, and a volume number in the form Volume 9 of 9. For example, a set of three volumes requires three labels: Volume 1 of 3, Volume 2 of 3, and Volume 3 of 3. Design an application that reads records that contain an author’s name, the title of the work, and the number of volumes. The application must read the records until eof is encountered and produce enough labels for each work. The flowchart must include a call symbol, at the beginning, to redirect the input to the external data file. create a solution algorithm using pseudocode create a flowchart using RAPTORarrow_forward

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.

- C++HurdleWords The HurdleWords class is mostly provided to you. HurdleWords is constructed from two files in the data/ folder: ● valid_guesses.txt (all 5 letter guesses considered to be valid words to guess), and ● valid_hurdles.txt (all words that may be selected to be the secret Hurdle.) ● Note: you may edit both text files if you’d like to add custom words to your game. HurdleWords stores all potential valid Hurdles from valid_hurdles.txt into a vector of strings (valid_hurdles_), and all valid guesses from valid_guesses.txt into an unordered set of strings (valid_guesses_). A set is simply a data structure that contains no duplicates and allows for a speedy lookup to check if a given element exists within the set. Because there are over 10,000 valid guesses, we store them in an unordered set to leverage their speediness, as you will need to check if a user-submitted guess is considered valid (i.e. their guess is considered a valid guess in the dictionary).

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.
