  • Gracefully handles non-numeric input.
• Clear Screen Effect:
  • Uses ANSI escape codes to clear the console for a fresh view on each step.
• Division Safety:
  • Checks for division by zero and shows an error instead of crashing.

• Works best in a terminal that supports ANSI escape codes
  (e.g., Linux terminal, macOS Terminal, Windows 10+ PowerShell/CMD).
