Write a method for
Integer instances named
celsiusToFahrenheit that, when sent to a number representing temperature in Celsius
answers twice that number plus 30.
Next, amend your
celsiusToFahrenheit method such that it displays
Performing an approximate temperature conversion every time that it is
Next, improve your
celsiusToFahrenheit method by having it add 40 to
the argument, multiply by 9/5, and subtract 40. Be sure that your
method answers with an integer.
Finally, change your
celsiusToFahrenheit method such that the receiver is in
Celsius degrees relative to absolute zero and the result answered is in
Fahrenheit degrees relative to absolute zero. Absolute zero is -273
For each change, comment on the corresponding benefit provided by procedure abstraction.
