1. All members may be public for this example
2. You will need three data members:
a. An array of 3 doubles to keep the votes
b. An array of 3 strings to place the candidates names
c. An array of 3 doubles to place the calculates vote
breakdown
3. You will need three methods:
a. A constructor that receives three strings and sets the names of
the candidates to these strings and set all the votes initially to
zero.
b. A "calcPercentages" method that has no arguments or return
values and simply calculates each vote percentage as one vote count
divided by the sum times 100
c. A "display Results" method that has no arguments and displays
each candidate's names and vote percentage.

Electronic Commerce - Airbnb
The focus of chapter 10 is on the topic of electronic commerce. E-commerce can be defined as using the Internet and the web to transact business. Global business to consumer e-commerce is soon expected to surpass $3 trillion dollars in sales. Needless to say, electronic commerce is revolutionizing the way we do business. By doing a search of the Internet or by other research methods, find how Airbnb has adopted an e-commerce business model.
Ponder the following questions (answer as many as you can):
1) What was the main driving force or strategy behind Airbnb decision to deploy e-commerce?
2) Has the adoption of e-commerce changed their traditional business model? In what ways?
3) Does their e-commerce business conflict with their traditional bricks and mortar business or does it enhance the traditional offering? Explain.
4) From table 10-5 on page 384 of the Laudon text, identify which Internet business model closely resembles the e-commerce model of this organization?
5) What role does social networking play in the marketing strategy of Airbnb?
6) Who are the organization's main competitors? How does this organization differentiate their e-commerce web site / offerings from their competitors?
7) Has the e-commerce aspect of their business been successful?
8) What recommendations would you make, if any, to improve the Airbnb web site or e-commerce features?

Develop a simulation program to simulate an 8-port Ethernet switch. The switch initially has no knowledge about the hosts connected to each port. It learns frame addresses and stores-and-forwards the frames. The input text file "in.txt" contains information of the incoming frames, one frame per line. There are 4 pieces of data per line: frame ID, arrival port, frame source address, and frame destination address. The frames arrive at the switch in the order of which they appear in the input file. Destination address "X" indicate a broadcast frame. The output text file "out.txt" has 8 lines. Each line lists all the frames departing from each port, Here is an example:
"in.txt" contains 5 incoming frames:
F1 P2 B--A
F2 P6 D--C
F3 P5 E--B
F4 P7 F--D
F5 P6 D--X
"out.txt" should list the departing frames on each port:
P1: F1 F2 F5
P2: F2 F3 F5
P3: F1 F2 F5
P4: F1 F2 F5
P5: F1 F2 F5
P6: F1 F4
P7: F1 F2 F5
P8: F1 F2 F5
please output out.txt for this input file input.txt
F1 P1 A--G F2 P1 B--H F3 P1 C--I F4 P2 D--E F5 P2 D--F F6 P7 G--A F7 P8 H--B F8 P8 I--C F9 P4 E--D F10 P4 F--D F11 P7 G--X F12 P1 B--G F13 P2 D--G F14 P4 E--G F15 P8 H--G F16 P1 A--D F17 P1 B--E F18 P1 C--F F19 P2 D--H F20 P8 H--I

This program (in python) will display a set of authors and the number of novels written by each author in both a table and a histogram. You will ask the user for all of the information. Using what you learned about incremental development, use the following approach to create your program:
Enter a title for the data: Number of Novels Authored You entered: Number of Novels Authored
Enter the column 1 header: Author name You entered: Author name Enter the column 2 header: Number of novels You entered: Number of novels
Enter a data point (-1 to stop input): Jane Austen, 6 Author: Jane Austen Number of Novel(s): 6
If the error occurs, output the appropriate error message and
prompt again for a valid data point. You can assume that if a comma
is present, then the data point is entered correctly.
Ex:
Enter a data point (-1 to stop input): Ernest Hemingway 9 Error: No comma in string. Enter a data point (-1 to stop input): Ernest Hemingway, 9 Author: Ernest Hemingway Number of Novel(s): 9
Number of Novels Authored Author name | Number of novels -------------------------------------------- Jane Austen | 6 Charles Dickens | 20 Ernest Hemingway | 9 Jack Kerouac | 22 F. Scott Fitzgerald | 8 Mary Shelley | 7 Charlotte Bronte | 5 Mark Twain | 11 Agatha Christie | 73 Ian Flemming | 14 J.K. Rowling | 14 Stephen King | 54 Oscar Wilde | 1
Jane Austen ****** Charles Dickens ******************** Ernest Hemingway ********* Jack Kerouac ********************** F. Scott Fitzgerald ******** Mary Shelley ******* Charlotte Bronte ***** Mark Twain *********** Agatha Christie ************************************************************************* Ian Flemming ************** J.K. Rowling ************** Stephen King ****************************************************** Oscar Wilde *
For this program, you can assume that the user will not enter duplicate author names

Latitude and Longitude are the two components used to exactly identify a specific spot on the Earth. Latitude provides the North/South direction and runs from 90 degrees north at the north poll to -90 degrees south at the south poll. The equator has a Latitude of zero.
Longitude provides the East/West direction and runs from the Prime Meridian that runs through Greenwich, England and has a Longitude of zero. Longitudes then run negatively to the west and positively to the east with the maximum Longitude being 180 degrees (or -180 degrees. They are the same Longitude.)
Usually Latitude and Longitude are usually depicted in degrees, minutes and second, but they can also be represented with just real numbers, which is how your class will need to be written. (FYI Lake Worth has a 26.61353 latitude and -80.057458)
Your assignment is to create a class called locCoordinates with the following properties and methods:
class locCoordinates
{
private:
double latitude;
double longitude;
string location;
public:
locCoordinates();
bool set(double, double, string)
bool setLatitude(double);
bool setLongitude(double);
void setLocation(string);
double getLatitude();
double getLongitude();
string getLocation();
void moveUpDown (double, string);
void moveLeftRight (double, string);
void move (double, double, string);
void print();
}
And here are the specifics for this class.
The constructor should set the latitude and longitude to zero, and the location to "Prime Meridian at Equator). It should not accept any parameters (and should not call the set function).
The set function will take the two numbers entered (latitude then longitude) and ensure they are correct. If either of the numbers are not within the correct range, then the location should be set to "Error", the value of the invalid entry should be set to zero and the function return a false. If everything is good it returns a true.
setLatitude will change the current value of Latitude. It also needs to check to make sure that it is a good latitude. If not correct the function should set the Latitude to zero and return false otherwise return true. In either case, the Location should be changed to "Unknown".
setLongitude does what setLatitude does, only to the Longitude.
setLocation just updates the location string in the class.
The gets return the values in the properties.
moveUpDown will pass in a double that may be either negative or positive. This value needs to be adjusted for the number of total degrees in the latitude, and then the latitude adjusted by that amount. The location would then also be updated.
moveEastWest does just like moveUpDown, but does it for Longitude.
move takes both a change in Latitude and Longitude and applies them along with setting the new location. (If I were coding this, I would probably just call moveUpDown and moveEastWest to do the work!!)
print will print out:
Latitude: 99.99999, Longitude: 999.99999 is at location: XXXXXX
You can implement this any way you want either by creating separate class header and implementation files, or by just putting everything in one big ole file with a main routine after the class definition. In the main routine, please set up a location with a bad input and show that a false is returned, then set one up with good input. Then use the move command to adjust the coordinates by an amount above 90 (or below -90) for latitude and above 180 (or below -180) for longitude. Then use the print function to print out the results.
