I need to render an image of a car continuously for a smooth visual experience in C# WinForms. It gets the location array (that has all the x,y of the tiles it should visit) from another function - assume it is already written.
write c program with features:
Register a Bunny: Store the bunny's name, poem, and initialize the egg count to 0.
Modify an Entry: Change the bunny's poem or update the egg count.
Delete a Bunny: Remove a registered bunny from the list.
List All Bunnies: Display all registered bunnies and their details.
Save & Load Data: Store bunny data in a file to persist between runs.
Use a struct to represent a bunny contestant.
Store data in a binary file (bunnies.dat) for persistence.
Use file I/O functions (fopen, fwrite, fread, etc.) to manage data.
Implement a menu-driven interface for user interaction.

- Lab 07: Java Graphics (Bonus lab) In this lab, we'll be practicing what we learned about GUIs, and Mouse events. You will need to implement the following: ➤ A GUI with a drawing panel. We can click in this panel, and you will capture those clicks as a Point (see java.awt.Point) in a PointCollection class (you need to build this). о The points need to be represented by circles. Below the drawing panel, you will need 5 buttons: о An input button to register your mouse to the drawing panel. ○ о о A show button to paint the points in your collection on the drawing panel. A button to shift all the points to the left by 50 pixels. The x position of the points is not allowed to go below zero. Another button to shift all the points to the right 50 pixels. The x position of the points cannot go further than the You can implement this GUI in any way you choose. I suggest using the BorderLayout for a panel containing the buttons, and a GridLayout to hold the drawing panel and button panels.…arrow_forwardIf a UDP datagram is sent from host A, port P to host B, port Q, but at host B there is no process listening to port Q, then B is to send back an ICMP Port Unreachable message to A.
