Textbook Question
Chapter 10, Problem 1E
Create an application class named LetterDemo that instantiates objects of two classes named Letter and CertifiedLetter and that demonstrates all their methods. The classes are used by a company to keep track of letters they mail to clients. The Letter class includes auto-implemented properties for the name of the recipient and the date mailed. Also, include a ToString() method that overrides the Object class’s ToString() method and returns a string that contains the name of the class (using CetType and the Letter’s data field values. Create a child class named CertifiedLetter that includes an auto-implemented property that holds a tracking number for the letter.

1.[30 pts] Computers generate color pictures on a video screen or liquid crystal display by
mixing three different colors of light: red, green, and blue. Imagine a simple scheme, with
three different lights, each of which can be turned on or off, projecting onto a glass screen:
We can create eight different colors based on the absence (0) or presence (1) of light

Each of these colors can be represented as a bit vector of length 3, and we can apply
Boolean operations to them.
a. The complement of a color is formed by turning off the lights that are on and turning
on the lights that are off. What would be the complement of each of the eight colors
listed above?
b. Describe the effect of applying Boolean operations on the following colors:
Λ
1. Red(100) ^ Magenta(101)= Blue(001)
2. Bue(001) | Green(010)=
3. Yellow(100) & Cyan(011)=
