In OOP, what does it mean to override a function?

To provide a new implementation in a derived class
To erase the implementation from the base class
To rename a function in the derived class
To call a base class function in the derived class

The correct answer is: To provide a new implementation in a derived class

When working with object-oriented programming, overriding a function means providing a new implementation in a derived class that replaces the implementation defined in the base class. This allows for customizing or extending the behavior of the function for specific needs in the derived class. Options B, C, and D are incorrect because they do not accurately describe the concept of overriding a function. Option B implies erasing the entire function, which would prevent any functionality from being inherited in the derived class. Option C suggests renaming the function, which would create a new function instead of overriding an existing one. Option D implies calling the base class function, which does not involve creating a new implementation in the derived class.
