Plan the project. In addition to the main function, each program should have at least one other

function. The function must have at least one parameter and should return a value.

Go the class team on replit and write and test your code in the designated project folder.

When your project is ready to be graded write a project report with the following format:

$$ Name of program $($include challenge number or title or both$)$

$$ Your name

$$ Name of your partner $($if you have one$)$

$$ A structure chart showing the functional decomposition of your program $($may be hand drawn

neatly and scanned into the report$)$

$$ An IPO chart for each user$-$defined function

$$ In your code add comments at the beginning of the script that summarizes the inputs, process,

and outputs for the program.

$$ For user$-$defined functions add comments to the function prototypes that describe the

preconditions and post condition for the function.

$$ Answer the following questions:

$1.$ What did you find most challenging with this program?

$2.$ What problems did you encounter and how did you solve them?

$3.$ What did you learn from writing this program?

Your final project must be in $.$pdf format. Upload your project report$($s$)$ to the assignment in Canvas and

submit.

Gas Prices

This project consists of a series of programs to analyze gas prices between April $1993$ and August $2013.$

You will be provided with a text file named GasPrices.txt$.$ The file contains the weekly average prices for

a gallon of gas in the United States, beginning on April $5$th$,1993,$ and ending on August $26$th$,2013.$

Figure $8-8$ shows an example of the first few lines of the file$$s contents:

Figure $8-8$ The GasPrices.txt file

Each line in the file contains the average price for a gallon of gas on a specific date. Each line is

formatted in the following way:

MM$-$DD$-$YYYY:Price

MM is the two$-$digit month, DD is the two$-$digit day, and YYYY is the four$-$digit year. Price is the average

price per gallon of gas on the specified date.

To get full credit for this project, you must complete programs $1,2$ and $3.$ You will get extra credit for

completing programs $4,$ and $5($you will get credit for each extra program you complete$).$

$1.$ Average Price Per Year: Calculate the average price of gas per year, for each year in the file.

$($The file$$s data starts in April of $1993,$ and it ends in August $2013.$ Use the data that is present

for the years $1993$ and $2013).$ Produce a report showing each year and the average gas price for

that year.

$2.$ Highest and Lowest Prices Per Year: For each year in the file, determine the date and amount

for the lowest price, and the highest price. Produce a report showing for each year, the lowest

price and date on which it occurred and the highest price and the date on which it occurred

$($show one year per line$).$

$3.$ Average Price Per Month: Calculate the average price for each month in the file. Produce a

report that shows each month and year and the average price for that month and year.

$4.$ List of Prices, Lowest to Highest: Generate a text file that lists the dates and prices, sorted from

the lowest price to the highest.

$5.$ List of Prices, Highest to lowest: Generate a text file that lists the dates and prices, sorted from

the highest price to the lowest$\mathrm{.}04-05-1993$:$1\mathrm{.}068$
