  4. // This program demonstrates temperature conversion between Celsius and
  5. // Fahrenheit using two functions:
  6. //
  7. //   float toFahrenheit(int celsius);
  8. //   float toCelsius(int fahrenheit);
  9. //
  10. // The program prints two tables:
  11. //   1. Celsius (0–100) to Fahrenheit (1 decimal place)
  12. //   2. Fahrenheit (32–212) to Celsius (2 decimal places)
  13. //
  14. // Formulas used:
  15. //   F = (C * 9/5) + 32
  16. //   C = (F - 32) * 5/9
