C++ Structure vs Class Inheritance

What is the difference between structure and class inheritance in C++?

In C++, both structures and classes can be used to create user-defined types, but they differ in default access levels. Structures default to public access, while classes default to private. This affects how inheritance works.

Can you give an example of how to use structure inheritance?

Sure! Here's a simple example:

struct Base {
    int value;
};

struct Derived : Base {
    void display() {
        std::cout << value;
    }
};

In this example, Derived inherits from Base.

What about class inheritance? Is it similar?

Yes, class inheritance is similar. Here's an example:

class Base {
    int value;
};

class Derived : public Base {
    void display() {
        std::cout << value;
    }
};

In this case, Derived inherits from Base with public access.

Are there any performance differences between using structures and classes?

Generally, there are no significant performance differences between structures and classes in C++. The choice between them usually depends on design preferences and access control.
