How do I use references in C++ classes?

Can you explain how to use references in C++ classes?

Sure! In C++, references allow you to create an alias for an existing variable. This is useful in classes for passing parameters.

What are the benefits of using references instead of pointers?

References are safer and easier to use than pointers. They cannot be null and do not require dereferencing.

Can you give me an example of a class using references?

Absolutely! Here's a simple example:

class MyClass {
public:
    void display(int &value) {
        std::cout << "Value: " << value << std::endl;
    }
};

In this example, display takes an integer reference.

Are there any limitations to using references in C++?

Yes, references must be initialized when declared and cannot be reseated to refer to another variable later.
