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.

Help, how do I write the pseudocode for the findMean function and flowchart for this?
