World Series Champions
If you have downloaded this book’s source code (the companion Web sire is available at www.pearsonhighered.com/gaddis), you will find a file named WorldSeriesWinners.txt. This file contains a chronological list of the winning teams in the World Series 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 that the World Series was not played in 1904 and 1994, so those years are skipped in the file.)

In the student sample program files for this chapter, you will find a text file namedGasPrices.txt. The file contains the weekly average prices for a gallon of gas in the UnitedStates, beginning on April 5th, 1993, and ending on August 26th, 2013. Figure 8-7 shows anexample of the first few lines of the file’s contents:Figure 8-7 The GasPrices.txt fileDescriptionEach line in the file contains the average price for a gallon of gas on a specific date. Each line isformatted in the following way:MM-DD-YYYY:PriceMM is the two-digit month, DD is the two-digit day, and YYYY is the four-digit year. Price is theaverage price per gallon of gas on the specified date.For this assignment, you are to write one or more programs that read the contents of the file andperform the following calculations:Average Price Per Year: Calculate the average price of gas per year, for each year in thefile.

The text file “studentMarks.txt” has been provided for you.
Each line contains the Last Name, First Name and 8 marks separated by spaces of a single student.
For each student in the file, adjust the file to include the average of their top 6 marks, rounded to 1 decimal place, at the end of the line.
For example, in the file, the line may say:
Mars, Bruno 82 82 85 94 65 79 81 90
Afterwards, it should be updated to say:
Mars, Bruno 82 82 85 94 65 79 81 90 Top6Avg: 85.7
Your program must define a function to determine the average of the top 6 marks. You may define more functions as needed for your program.

If you have downloaded this book’s source code (the companion Web site is available at www.pearsonhighered.com/gaddis), you will find a file named WorldSeriesWinners.txt. Also is file is attached to the dropbox as well as in the downloads for this chapter. This file contains a chronological list of the winning teams in the World Series from 1903 through 2009. (The first line in the file is the name of the team that won in 1902, and the last line is the name of the team that won in 2009. Note that the World Series was not played in 1904 or 1994, so those years are skipped in the file.)
Write a program that lets the user enter the name of a team, and then displays the number of times that team has won the World Series in the time period from 1903 through 2009. You should list the years cronoligically.
