What does the increment method do in the Counter class?
What does the increment method do in the Counter class?
The increment method in the Counter class adds one to the counter instance variable, increasing its value by 1.
What does the get_value method in the Counter class return?
What does the get_value method in the Counter class return?
The get_value method in the Counter class returns the current value of the counter instance variable.
What does the Counter constructor with two arguments do?
What does the Counter constructor with two arguments do?
The constructor in the Counter class that takes two int arguments initializes both the counter and limit instance variables. These values are set based on the arguments provided when creating a new Counter object.

Class Definitions Summary
-
Counter Class
- Encapsulates a counter with a variable initialized to zero.
- Contains methods to increment the counter by 1 and retrieve its current value.
- Optionally includes a decrementing functionality and a limit for the counter in advanced versions.
-
Player Class
- Manages player information with attributes for name (string) and score (integer).
- Methods allow setting player name and score, as well as retrieving these values.
-
ContestResult Class
- Tracks results of a contest with attributes for winner, second place, and third place (all strings).
- Provides methods to set and get the values of each placement.
-
WeatherForecast Class
- Handles weather forecasting with attributes for sky conditions (string), high temp (int), and low temp (int).
- Methods set and get these values, allowing updates and retrieval of the latest forecast information.
Key Features of Classes
- Initialization: Instance variables typically initialized in class definitions.
- Methods: Include both mutator (set) and accessor (get) methods for manipulating and retrieving instance variables.
- Encapsulation: Each class bundles data and the corresponding methods, maintaining a clear structure for data management.
Additional Notes
- Constructors are optional, depending on the specific requirements of the class.
- Classes can be extended with functionalities, such as limits on values or additional state management.
