Program $01$:

You work for a bookstore and are responsible for keeping track of the number of

books sold on a weekly basis. At the end of the week, you need to enter the

number of books sold each day of the week and determine the following $($on a

weekly basis$)$:

Total number of books sold that week

The highest number of books sold that week

The lowest number of books sole that week

The average number of books sold that week

You need to use $a^{\text{'}}$ While' loop to allow the user to enter the books sold each day

of the week.

For example, if on day one you sold $5$ books, day two you sold $15$ books, day three

you sold $1$ book, day four you sold $8$ books, day five you sold $4$ books, day six you

sold zero books, and day seven you sold $11$ books, this would total $44$ books sold

that week. In addition to that, the highest number of books sold that week is $15$

and the lowest number of books sold that week is zero. The average number of

books of books sold that week is $6\mathrm{.}28$ books.
