Objectives:

Continue practicing past concepts

Practice using files

Practice using vectors

Background:

Comma separated vector $($CSV$)$ files are a type of text file $($specifically using the $.$ csv file

extension$).$ These can be viewed in any plain text editor, but they can also be represented in

spreadsheet programs $($ie$,$ Excel$).$ Essentially, it defines columns by commas on each line.

Where each row is then actually a row in a table.

Their plain text version looks something like this:

Number $1,$ Number $2,$ Number $3$

$1,2,3$

$4,5,6$

$7,8,9$

Whereas, if you'd show the same file in Excel, it'd look like this:

Assignment:

Your job is to create a program that takes in a standard text $(.$txt$)$ file and converts that to a CSV

$(.$csv$)$ file. Each item will be designated by an individual item in a row in the text file. Then, we'll

define when you should have a new row in the CSV file by an exit character $-1.$

Would be translated to a CSV file as:

$1,2$

$3,4$

Your program should, take in a base filename $($WITHOUT AN EXTENSION$),$ open that filename

with $.$ txt added and verify the existence in a loop. Once you have a valid file, read the contents

into a vector and close the input file. Then, open an output file of the input filename with $.$ csv

added and write the contents of the vector appropriately.

Your program should end with the following files existing:

filename, txt

filename.csv

A couple sample text files have been provided to use.

Milestones:

You must receive a check$-$off for each item to receive full credit on the lab. You may show the

milestones incrementally, or receive a check off for multiple in one demo depending on your

progress.

Examples of each milestone are included.

Milestone $1$:

Take user input for the file without an extension. Loop until the file exists. Must show:

Looping until a file that exists is entered

No extension is taken from the user

Milestone $2$:

Read the contents of your file into a vector. Must show:

File contents printed to the screen FROM A VECTOR

To get checked off for this one, you must show in the demo, a vector is being read from

to display to the screen, not printing to the screen as you're reading the file

Milestone $3$:

Writing into a CSV file. Must show:

A successfully created CSV file

All items on one row, but multiple columns

Milestone $4$:

Properly formatting the CSv file. Must show:

$-1$ is not added to the file

Where $-1$ would be$,$ there is instead a new row

There is NO floating comma at the end of each row

Milestone $5$:

Works with multiple files. Show milestone $5$ with all sample files provided to you. Must show:

Ran FRESHLY Cannot have prepared files to show all at once these must be generated by the program, in real time.
