What are the main ways of interacting with objects in programming?

The main ways of interacting with objects in programming include:

• Calling methods — objects provide methods that can be invoked to perform actions or retrieve data.
• Accessing properties — reading or modifying the values of an object's properties.
• Message passing — a concept from object-oriented programming where an object receives a message (method call) and responds to it.
• Using interfaces — interacting through predefined contracts, allowing work with objects abstractly.

Example in C#:

class Person {
    public string Name { get; set; }
    public void SayHello() {
        Console.WriteLine($"Hello, my name is {Name}");
    }
}

var person = new Person { Name = "Alex" };
person.SayHello(); // method call
string name = person.Name; // access to property
