Your app must take in at least one number and one string from the user that will help to make the decision. All of this information will be used as part of the decision-making process. In addition, your code must include at least one function used to update the screen. You will submit ●くろまる Your final app ●くろまる A video that shows your program running ●くろまる This completed project-planning guide App Requirements ●くろまる At least one number and one string used to make and report a decision with a conditional statement ●くろまる A function which updates the screen and is called at least twice in the program ●くろまる Conditional statement includes at least one logical operator ( &&, || or ! ) ●くろまる There are at least three different possible output answers (i.e. "Yes, you can adopt a cat!", "No, you can’t adopt a cat", and "Congratulations, you can adopt a kitten!). ●くろまる Every function contains a comment explaining purpose and functionality ●くろまる Clear and easy to navigate user interface ●くろまる Cleanly written code which is free of errors Steps ●くろまる Brainstorm an app idea for making a decision ●くろまる Interview classmates for ideas on what information would be needed to make the decision ●くろまる Draft a flowchart of the decision making process ●くろまる Design your app’s user interface ●くろまる Design and program your app in App Lab ●くろまる Collect feedback from othersand update your app ●くろまる Record a screen capture of your app being used ●くろまる Submit your final app Explore : Explore the two sample apps in levels 1 and 2 and answer the following questions: Level 1: ●くろまる What does this app do? This app shows the best restaurants the user should buy
based on their budget and taste for food. ●くろまる What are the inputs? The clicks from the buttons and drop-down menus. ●くろまる What are the outputs? The text displayed on the bottom changes. ●くろまる What variables do you think would be necessary for this app to work? Price, foodType. ●くろまる What kinds of conditional logic do you think are necessary to make it work? Things like if the food type is Chinese && the budget is over 25,ドル display Din Tai Fung, etc. Uses && operators. Also likely uses if, else, else if for each type of budget. ●くろまる How could a function be used in this app? It could reduce the amount of code needed to update the screen each time, instead of having to write it over and over. It could also be used to repeat the code that checks the budget and food type. Level 2: ●くろまる What does this app do? Shows users the best type of activity/exercise to do at each time of the day with regard to their activity level. ●くろまる What are the inputs? Drop-down menus clicked, and options clicked. ●くろまる What are the outputs? Displayed text on the bottom with our custom name string along with the best activity. ●くろまる What variables do you think would be necessary for this app to work? Username, time of day, activity level ●くろまる What kinds of conditional logic do you think are necessary to make it work? Uses not, &&, and == to show the best exercise. ●くろまる How could a function be used in this app? A function could be used to make the code for figuring out the best type of activity. It could be made once and checks each time the user changes the value of the activity type. Investigate Step 1. Brainstorm App Ideas: Your app should be designed to help a user make a decision. For this project your user is your classmate. The decision can be small or big, like what to eat for lunch or where to apply for a job. Keep in mind how your idea might help solve a problem for your user. Idea 1: Europe Travel Agency App Idea 2: Should I buy a hamster? Idea 3: Best place for weddings. Step 2. Choose One Idea: Pick the one that you are most interested in. App Idea: Create an app that decides if a user should get a hamster. It takes in account the age, and amount of money the user has. If they aren’t old enough or have enough money, they are told not to get a hamster. Step 3. Interview Your Potential Users: To design your app you’ll need to understand your users. 2
For this project your users can be anyone - classmates, family, or friends. You need to understand what they already know about your topic. Interview at least 2 users. Indicate a first name and a last initial and their answers to the questions below(10 points each): Name What information is needed to make this decision? Prajitha Panakkal. How much money do we need to spend per hamster? Joshy Mathew At what age should you get a hamster? Step 4: Storing information: What variables will be used to store information? Name Information Stored Variable Type (string, number, Boolean) Ex: age The age of the user number name The name of the user string money The budget of the user number age The age of the user number Step 5: Flowchart: Draft a flowchart to show the decision making process Example: 3

Component Purpose Start your flowchart with a question. What decision are you trying to make? Baggies are used to represent the variables which store information. In your flowchart, draw a small rectangle for the variables. A diamond represents a decision point, based on the original question. Write the Boolean expression that will be used to determine the answer. True and False arrows designate the paths taken, based on the result of a decision (diamond). Note that every decision may have only 2 possible paths that result from it, one for true and one for false. A rectangle at the end of a decision path represents a possible result. A simple arrow indicates that we are moving from one action to the next without considering any decision. These will generally be used to link a set of actions to be completed one after the other. Flowchart 4
Design 5 Should I buy a hamster? I can if I am over 10 and have more than 40ドル. Money Name Age [Name] can’t adopt a hamster [Name] can adopt a hamster age> 10 Money >= 40 Fals e Tru e True Fals e
Step 6. Design User Interface: In the space below draw a rough sketch of your user interface. This means you should include all the buttons, text, and images that the user will be able to use. Write notes or draw arrows showing how different user interface elements should work. Note: There are no screen requirements for this app - you may use one or more screens. You can sketch below or create the screens in the app lab and copy and paste a screenshot below. Prototype Step 7. Start Building Your App: Build your app. Along the way make sure you: ●くろまる Use the design you drew as a starting point, but it’s OK to update as you go. ●くろまる Reference the flow chart when setting up your conditional statements ●くろまる Use your debugging skills to check that your app is working ●くろまる Comment all functions explaining purpose (what does it do) and functionality (how does it work) - also include header comments explaining what the app does. The app lab has levels 2-4 to walk you through the beginning steps of creating the components of your app Test Step 8. Testing: You will need to test your app to make sure it works as expected. To do that find at least two users to run your app. While they use the app watch them to see if anything is broken or confusing. Afterwards ask them to share any specific improvements they’d like to see. 6

Link to unlisted video: (Canvas media wasn’t working whatsoever) https://youtu.be/L4wCScnlVaY Your video must demonstrate your program running, including: ●くろまる Input to your program ●くろまる At least one aspect of the functionality of your program ●くろまる Output produced by your program Check these suggestions if you are not sure how to record your screen. Speaking Assignment Instructions. 7
Question 1: Provide a written response that: ●くろまる describes the overall purpose of the program ●くろまる describes the functionality of your app ●くろまる describes the input and outputs of your app (Approx 150 words) The purpose of my app is to create an app where people can input their details and see if they would be able to take care of a hamster. They must be over 10 years old and have atleast 40 dollars. The inputs are the clicks from the drop down menus, the characters inputted in the name field, and the button presses on the money inputs. The outputs of my app are changes in the variables money, age, and name. These are displayed on the box at the bottom. Question 2: This project was created using a development process that required you to incorporate the ideas of your partner and feedback from your classmates. Provide a written response that describes one part of your app that was improved through input from EITHER your partner or feedback you received from classmates. Include: ●くろまる Who specifically provided the idea or recommendation ●くろまる What their idea or recommendation was ●くろまる The specific change you made to your app’s user interface or functionality in response to the recommendation ●くろまる How you believe this change improved your app (Approx 150 words) Prajitha provided a great idea to increase the size of the hamster photo as that was one of the main focuses of our app. Secondly, Joshy said to increase the size of the money counter, as it was hard to see. Both of these changes allowed me to create a more cohesive look that worked better for my users. It become more accessible and improved the readability of the overall app. I did this by increasing the font size of the text. 8
