This problem contains loops, sorting arrays, random generation, and variable matching.

Include an analysis (data requirements) and algorithm in your reply.

Write a “lottery engine” program to simulate drawing lottery numbers. You will draw 7 numbers, randomly selected from 1 to 16.

a) Allow the user to enter their own selection of numbers first,

Example numbers: 2 3 7 9 10 11 15

b) then run your “lottery engine” to select the “winning numbers”. Numbers are drawn randomly.

Use the clock as the seed value for your random function (Hint: use “srand(clock());” ).

c) Be sure to remove duplicate entries.

d) Print out the draw result as it was generated (unsorted), then sort the array and print out the sorted numbers.

Example output:

“

Draw unsorted: 2 12 16 14 7 13 1

Draw sorted: 1 2 7 12 13 14 16

“

e) Then print out the matching numbers selected by the user:

f) Also print the sorted user selection and draw results and matching numbers to a TXT file called “Results.txt”.

Example output

“

Draw sorted: 1 2 7 12 13 14 16

User’s sorted: 2 3 7 9 10 11 15

Matching numbers: 2 – 7

Given an integer named area which represents the area of a rectangle, write a function minPerimeter that calculates the minimum possible perimeter of the given rectangle, and prints the perimeter and the side lengths needed to achieve that minimum. The length of the sides of the rectangle are integer numbers. For example, given the integer area = 30, possible perimeters and side-lengths are: (1, 30), with a perimeter of 62 (2, 15), with a perimeter of 34 (3, 10), with a perimeter of 26 (5, 6), with a perimeter of 22 Thus, your function should print only the last line, since that is the minimum perimeter. Some example outputs:

>>>minPerimeter(30)

22 where rectangle sides are 5 and 6.

Scenario

Congratulations! Your App Development Proposal has received approval after being shared with both your client and the mobile application development team at Mobile2App. It is now time to construct a UI based on your original proposal. You must supply the client with a complete UI design that is easy to understand and demonstrates a creative theme and layout for the finished application.

Directions

Open the Android Studio Layout Editor to begin creating the UI for your app. Be sure to use the Install Android Studio resource and the Build a Simple User Interface resource, both linked in the Supporting Materials section, to get started with this software. Throughout this project, continue to reference the App Development Proposal you completed in Project One while paying particular attention to the section on UI Design. Also be sure to let the Android Design and Quality Guidelines document, which is linked in the Supporting Materials section, guide your decisions.

Your completed UI should include all of the screens needed for your app to operate but the UI will not yet be functional. You will only be creating the UI components for this project as the supporting code will be completed in Project Three.

1. Create UI with appropriate design elements to support a user logging in (1 screen). Your UI must include a login screen, that contains the following:
   • Fields for the user to provide a username and password
     • Note that the password element should be configured in a way that obscures any text that is typed into the field. This means the text will need to be visually converted into dots.
   • A button for the user to submit their username and password
   • A button for the user to create a new login if it is their first time using the application
     • Note that to simplify the account creation process, you can use the same login screen for this purpose. Create a button that will add the username and password into the database if it does not already exist.
   • Any other fields or elements that are necessary to make your application visually appealing, intuitive, and usable

CASE 2

Pandora is the Internet’s most successful subscription radio service. In May 2014, Pandora had 77 million registered users. Pandora accounts for over 9 percent of total U.S. radio listening hours. The music is delivered to users from a cloud server, and is not stored on user devices. It’s easy to see why Pandora is so popular. Users are able to hear only the music they like. Each user selects a genre of music based on a favorite musician or vocalist, and a computer algorithm puts together a “personal radio station” that plays the music of the selected artist plus closely related music by different artists. The algorithm uses more than 450 factors to classify songs, such as the tempo and number of vocalists. These classifications, in conjunction with other signals from users, help Pandora’s algorithms select the next song to play. People love Pandora, but the question is whether this popularity can be translated into profits. How can Pandora compete with other online music subscription services and online stations that have been making music available for free, sometimes without advertising? “Free” illegally downloaded music has also been a significant factor, as has been iTunes, charging 99 cents per song with no ad support. At the time of Pandora’s founding (2005), iTunes was already a roaring success. Pandora’s first model was to give away 10 hours of free music and then ask subscribers to pay $36 per month for a year once they used up their 10 free hours. Result: 100,000 people listened to their 10 hours for free and then refused to pay for the annual service. Facing financial collapse, in November 2005 Pandora introduced an ad-supported option. In 2006, Pandora added a “Buy” button to each song being played and struck deals with Amazon, iTunes, and other online retail sites. Pandora now gets an affiliate fee for directing listeners to sites where users can buy the music. In 2008, Pandora added an iPhone app to allow users to sign up from their smartphones and listen all day if they wanted. Today, 70 percent of Pandora’s advertising revenue comes from mobile. In late 2009 the company launched Pandora One, a premium service that offered no advertising, higher quality streaming music, a desktop app, and fewer usage limits. The service costs $4.99 per month. A very small percentage of Pandora listeners have opted to pay for music subscriptions, with the vast majority opting for the free service with ads. In fiscal 2013 Pandora’s total revenue was $427.1 million, of which $375.2 million (88 percent) came from advertising. Pandora has been touted as a leading example of the “freemium” revenue model, in which a business gives away some services for free and relies on a small percentage of customers to pay for premium versions of the same service. If a market is very large, getting just 1 percent of that market to pay could be very lucrative— under certain circumstances. Although freemium is an efficient way of amassing a large group of potential customers, companies, including Pandora, have found that it is challenging to convert people enjoying the free service into customers willing to pay. A freemium model works best when a business incurs very low marginal cost, approaching zero, for each free user of its services, when a business can be supported by the percentage of customers willing to pay, and when there are other revenues like advertising fees that can make up for shortfalls in subscriber revenues. In Pandora’s case, it appears that revenues will continue to come overwhelmingly from advertising, and management is not worried. For the past few years, management has considered ads as having much more revenue-generating potential than paid subscriptions and is not pushing the ad-free service. By continually refining its algorithms, Pandora is able to increase user listening hours substantially. The more time people spend with Pandora, the more opportunities there are for Pandora to deliver ads and generate ad revenue. The average Pandora user listens to 19 hours of music per month. Pandora is now intensively mining the data collected about its users for clues about the kinds of ads most likely to engage them. Pandora collects data about listener preferences from direct feedback such as likes and dislikes (indicated by thumbs up or down on the Pandora site) and “skip this song” requests, as well as data about which device people are using to listen to Pandora music, such as mobile phones or desktop computers. Pandora uses these inputs to select songs people will want to stick around for, and listen to. Pandora has honed its algorithms so they can analyze billions more signals from users generated over billions of listening minutes per month. As impressive as these numbers are, Pandora (along with other streaming subscription services) is still struggling to show a profit. There are infrastructure costs and royalties to pay for content from the music labels. Pandora’s royalty rates are less flexible than those of its competitor Spotify, which signed individual song royalty agreements with each record label. Pandora could be paying even higher rates when its current royalty contracts expire in 2015. About 61 percent of Pandora’s revenue is currently allocated to paying royalties. Advertising can only be leveraged so far, because users who opt for free ad-supported services generally do not tolerate heavy ad loads.
