Question

in a single file, you wrote a bike class and used this line of code in the program. bikea = bike(acme,111)
which statement is true about the code in your file?
the code to define your class (beginning with \class bike\) must come before the line \bikea = bike(acme,111).\
the code to define your class (beginning with \class bike\) can come either before or after the line \bikea = bike(acme,111).\
the code to define your class (beginning with \class bike\) cannot be in the same file as the line \bikea = bike(acme,111).\
the code to define your class (beginning with \class bike\) must come after the line \bikea = bike(acme,111).\

Explanation:

In programming, a class must be defined before it can be instantiated. The line bikeA = bike('Acme',111) is instantiating an object of the bike class. So the class definition (starting with class bike) must precede this instantiation line.

Answer:

The code to define your class (beginning with "class bike") must come before the line "bikeA = bike('Acme',111)."
