Use Cases:
Understanding when and how to use Console.CursorVisible is crucial for various scenarios, such as:
1. Enhancing User Experience:
- In applications where user interaction happens primarily through the console, showing or hiding the cursor at appropriate times can enhance the user experience.
- For instance, in a text-based game, we might want to hide the cursor during gameplay to prevent distractions.
2. Custom Console Interfaces:
