are used for generic programming. Options Inheritance Virtual Functions Templates None of these

The question is asking about a feature used for generic programming. Let's break down the options:

1. Inheritance: This is a fundamental concept in object-oriented programming but not specifically related to generic programming.

2. Virtual Functions: These are used to achieve polymorphism in object-oriented programming, allowing derived classes to override behavior, but they are not related to generic programming.

3. Templates: This is a feature in C++ (and other languages) that facilitates generic programming, allowing functions and classes to operate with any data type.

4. None of these: This option implies that none of the above are used for generic programming, which is incorrect because templates are specifically designed for that purpose.

Final Answer

The correct answer is Templates.
