How can I improve code reusability in C++?

You can improve code reusability in C++ by using classes, templates, and inheritance. Would you like examples?

Yes, please provide an example using classes.

Sure! You can create a base class for common functionality and then derive specific classes from it. This way, you can reuse the base class methods.

What about using templates?

Templates allow you to write generic functions and classes. For instance, a template function can work with any data type, enhancing reusability.

Can you show me a simple template example?

Absolutely! Here's a simple template function that swaps two values:

template <typename T>
void swap(T &a, T &b) {
    T temp = a;
    a = b;
    b = temp;
}
