Carpet Size
You have been asked to create an application for a carpet sales and installation business. The application should allow the user to enter the length and width of a room and calculate the room’s area in square feet. The formula for this calculation is
In this exercise, you will gain practice using Steps 1 through 6 of the
- 1. Clearly define what the application is to do.
- 2. Visualize the application running on the computer and design its user interface.
- 3. Determine the controls needed.
- 4. Define the values of each control’s relevant properties.
- 5. Determine the event handlers and other code needed for each control.
- 6. Create a flowchart or pseudocode version of the code.
Step 1: Describe the following
characteristics of this application:
Purpose
Input
Process
Output
Step 2: Draw a sketch of the application’s form and place all the controls that are needed.
Step 3: Make a list of the controls you included in your sketch. List the control type and the name of each control.
Step 4: List the value of the Text property for each control, as needed. (Remember, some controls do not have a Text property.)
Step 5: List each method needed. Give the name of each method and describe what each method does.
Step 6: For each method you listed in Step 5, draw a flowchart or write pseudocode.

Thanksarrow_forwardcan you solve this pleasearrow_forwardIn the previous homework scenario problem below: You have been hired by TechCo to create and manage their employee training portal. Your first task is to develop a program that will create and track different training sessions in the portal. Each training session has the following properties: • A session ID (e.g., "TECH101", "TECH205") • A session title (e.g., "Machine learning", "Advanced Java Programming") • A total duration in hours (e.g., 5.0, 8.0) • Current number of participants (e.g., 25) Each session must have at least a session ID and a total duration and must met the following requirements: • The maximum participant for each session is 30. • The total duration of a session must not exceed 10 hours. • The current number of participants should never exceed the maximum number of participants. Design an object-oriented solution to create a data definition class(DDC) and an implementation class for the session object. In the DDC, a session class must include: • Constructors to…arrow_forward

- Create 2 charts using this data. One without using wind speed and one including max speed in mph. Write a Report and a short report explaining your visualizations and design decisions. Include the following: Lead Story: Identify the key story or insight based on your visualizations. Shaffer’s 4C Framework: Describe how you applied Shaffer’s 4C principles in the design of your charts. External Data Integration: Explain the second data and how you integrated it with the Halloween dataset. Compare the two datasets. Attach screenshots of the two charts (Bar graph or Line graph) The Shaffer 4 C’s of Data Visualization Clear - easily seen; sharply defined• who's the audience? what's the message? clarity more important than aestheticsClean - thorough; complete; unadulterated, labels, axis, gridlines, formatting, right chart type, colorchoice, etc.Concise - brief but comprehensive. not minimalist but not verboseCaptivating - to attract and hold by beauty or excellence does it capture…arrow_forwardHow can I resolve the following issue?arrow_forwardI need help to resolve, thank you.arrow_forward
