Exit

For options $1$ do the following:

Write the information into a text file, MUST be written in a tabular format again $($must

include header row$).$ Name the file "book inventory"

Write the information into a csv file. Also must include header row and Overall total of

course.

When writing book price in csv file, add the dollar sign $"$$$"$ next to the price.

Dollar sign must be added next to overall total also

The Overall total MUST be listed under the same column that shows book price.

Name the file "book inven CSV$"$

For options $2,$ Search by author, do the following:

In M$4$Pro, the user had to enter the exact author name $($the entire name and was case

sensitive too$),$ not anymore. Make sure the following is applied

The program is to convert the name entered to the correct case $($use string

methods$)$

The program should find the books even if only part of the name is entered. So

for instance, if the user enters "rowl" $,$ the program is to display all the books

for the author$($s$)$ that have names that contain the word$/$name that was

entered.

If books are found, Write the information into a text file, Again MUST be written in a

tabular format again $($must include header row$).$

The file name would depend on the name that was entered. So if the user entered

"rowl", the file is to be named "rowl books"

Create a csv file that has the same name. Again, must include header row and Overall

total of course.

When writing book price in csv file, add the dollar sign $"$$$"$ next to the price.

Dollar sign must be added next to overall total also

The Overall total MUST be listed under the same column that shows book price.

File name again depends on the name searched. So if "rowl" was entered, the

file is to be named "rowl books CSV$"$

For options $3,$ Search by book name:

You won't have to create a file BUT, string evaluation must be done. So here's what you'll have to do

here:

In M$4$Pro, the exact book name had to be entered. That shouldn't be required anymore.

The program is to convert the title entered to the correct case $($use string methods$)$

The program should find the book$($s$)$ that have that given title.

$*$ Even if only part of the title is entered. So for instance, if the user enters "and the, all

the books that contain that word or set of words are to be displayed.

For options $4,$ Search by price range:

Again write the information into two files, txt file and csv file

The file names will depend on the price range entered. For instance if starting was $10$ and

ending price $19,$ the file$($s$)$ could be named as following "books$\_10\_19"$
