A polygon is called convex if every line segment from one vertex
to another lies entirely within the polygon. To triangulate a
polygon, we take some of these line segments, which don’t cross one
another, and use them to divide the polygon into triangles. Prove,
by strong induction for all naturals n with n ≥ 3, that every
convex polygon with n sides has a trian-gulation, and that every
triangulation contains exactly n − 2 triangles. (Hint: When you
divide an n-gon with a single line segment, you create an i-gon and
a j-gon for some naturals i and j. What does your strong inductive
hypothesis tell you about triangulations of these
polygons?)

(a) Create a function called polygon that draws a polygon in a
polar plot. Your function should have a single input parameter –
the number of sides.

Write a C++ function called parse that reads one line
of user input from the keyboard and creates an array of the strings
found in the input. Your function should be passed the
array and a reference variable that is to be assigned the length of
the array. Prompt the user and read the input from
within the function.
For example: If the user inputs copy this
that, the resulting array would have length 3 and contain the
strings “copy”, “this”, and “that”....

upscale retailer, “the customer is always right” is not just a
