// Description: This program will prompt the user for both an input and an
// output file name. Afterwards, it will prompt for a target word.
// The program opens the file and reads all the words in the file and keeps
// track of how many times that word appears. It writes (appends) the word
// and the number to the output file. It continues this until the user
// types "exit".

using distance forumla and stuff could also be used

I'll will do it with the assumption that it is a nice rectangle

if there is rotation a small change would work

figure 1.25 use a lot of vectors for the max instead of using

Not Sure if I had to make something else, like point which rectangle is it or
I have ro give a name to each rectangle and then after finding the one with the
max area do a for loop to search which rectangle it was that had that area
or something else, but to do that, it feels like it would require a lot more code
than what it is asking for, or make the areas into vector of arrays where
each array has a form {RectName, Area, Perimete} and then do some stuff with this
but oing so means you would somewhat had to mess with the findMax to make it work
but findMax feels according to the question feels like we shouldn't mess with.
So I just print the result of which area and perimeter are the biggest.
