*Object Oriented Programming* (OOP) is a programming paradigm that promotes the design of programs by having different objects interacting together to solve a problem. C++ is one of the programming languages that promotes object oriented programming, allowing programmers to create their own classes from scratch or derive them from other existing classes. Other languages that promote OOP are Java, Python, Javascript and PHP.

When an object class we need to use in our program has not been predefined in a library, we need to declare and implement our own class. To do this, we define *classes* that contain data with certain *properties* or *attributes* and actions that we want to carry out with this data through the use of *methods* or *member functions*. This way, we can organize the information and processes in *objects* that have the properties and methods of a class. In today's laboratory experience you will practice defining a class and implementing some of its methods by completing a program that simulates a basketball game between two players, maintaining the score for the game and the global statistics for the two players.

The skeleton for the program that we provide simulates a basketball game between two players. The successful throws into the basket receive two points. The data is initiated with the name of each player and the global statistics in the "tournament": total of games played, attempted throws, successful throws and rebounds. The program includes random functions and formulas to determine the player that attempts a throw, if the player scores, and the player that takes the rebound. During the simulated game the score for each player is kept and each player's data is updated. At the end of the game, a table with the statistics is displayed.

For this laboratory experience, you will define the `BBPlayer` class that contains the attributes and methods that are described below. Since some of the functions that are already defined in the provided code use attributes and methods of this class, it is important that you use the same names that we indicate. The commented code in the `main` function and in `test_BBPlayer` will help you determine the type of data the method should return, the types the parameters should have, and the order in which they are included in the function declaration.

The skeleton for the program also includes the `test_BBPlayer` function that does unit tests to each of the functions in the program. The tests are commented and, as you define each function, you will remove the comment, test and modify the function, until the test for that function is passed. Once all of the functions are ready and have passed the tests, the whole program is tested by removing the necessary comments in the `main` function.
