Question

You've been hired by Text Turtles to write a C++ console application that determines the reading grade level of the text in a file. The text comes from two files: SampleText1.txt and SampleText2.txt. Sample text1= It has often been said
there's so much to be read
you never can cram
all those words in your head.
So the writer who breeds
more words than he needs
is making a chore
for the reader who reads.
That's why my belief is
the briefer the brief is
the greater the sigh
of the reader's relief is.

Sample text 2=

Four score and seven years ago our fathers brought forth on
this continent, a new nation, conceived in Liberty, and
dedicated to the proposition that all men are created equal.
Now we are engaged in a great civil war, testing whether
that nation, or any nation so conceived and so dedicated,
can long endure. We are met on a great battlefield of that
war. We have come to dedicate a portion of that field, as a
final resting place for those who here gave their lives
that that nation might live. It is altogether fitting and
proper that we should do this. But, in a larger sense, we
cannot dedicate, we cannot consecrate, we cannot hallow
this ground. The brave men, living and dead, who struggled
here, have consecrated it, far above our poor power to add
or detract. The world will little note, nor long remember
what we say here, but it can never forget what they did
here. It is for us the living, rather, to be dedicated here
to the unfinished work which they who fought here have thus
far so nobly advanced. It is rather for us to be here
dedicated to the great task remaining before us, that from
these honored dead we take increased devotion to that cause
for which they gave the last full measure of devotion, that
we here highly resolve that these dead shall not have died
in vain, that this nation, under God, shall have a new birth
of freedom, and that government of the people, by the
people, for the people, shall not perish from the earth.

Place the files where your app can find them. File SampleText1 will be used to test your app. File SampleText2 will be used for your final run.In your app, attempt to open the input file. Print an error message if the file doesn't open. Otherwise, read one line at a time from the file and keep count of the number of lines read. For each line read, loop through the line and count the number of:

          ● Alphanumeric characters – use function isalnum.

          ● Punctuation characters – use function ispunct.

          ● Spaces.

          ● Other characters – this should be zero.

          ● Number of sentences – this is the number of periods (.).

          ● Number of characters.

After reading the file, these counts will be for the entire file. Then calculate the following:

          ● Number of words – this is the number of spaces plus the number of sentences.

          ● Number of letters in words – this is the number of alphanumeric characters.

          ● Factor1 = number of letters in words / words * 100

          ● Factor2 = sentences / words * 100

          ● Reading level = (0.0588 * Factor1) – (0.296 * Factor2) – 15.8

Use formatted output manipulators (setw, left/right) to print the following rows:

          ● Alphanumeric characters.

          ● Punctuation characters.

          ● Spaces.

          ● Other characters.

          ● Number of characters.

          ● Number of sentences.

          ● Number of words.

          ● Number of letters in words.

          ● Factor 1.

          ● Factor 2.

          ● Reading level.

And two columns:

          ● A left-justified label.

          ● A right-justified value.

Define constants for the file names and column widths. Format all real numbers to one decimal place. For file SampleText1, the output should look like this:
