What are the differences between structs and classes in programming?

Structs and classes are both used to create complex data types, but they have some key differences. Structs are typically value types, while classes are reference types. This means that structs are copied when passed around, whereas classes are passed by reference.

Can you give me an example of a struct and a class in code?

Sure! Here's a simple example in C#:

struct Point {
    public int X;
    public int Y;
}

class Circle {
    public Point Center;
    public int Radius;
}

What are the advantages of using classes over structs?

Classes support inheritance, which allows for more complex relationships between types. They also can have destructors and can implement interfaces, which structs cannot.

Are there any performance differences between using structs and classes?

Yes, structs can be more efficient for small data types because they are allocated on the stack, while classes are allocated on the heap, which can introduce overhead.
