Any class or struct that implements the interface must implement all its members. Any class or struct that implements the interface must implement all its members. By using interfaces, we may include behavior from multiple sources in a class. It is important in C# because the language doesn't support multiple inheritance of classes. We must use an interface for simulating inheritance for structs, because they can't actually inherit from another struct or class.

Task 5-1. Develop interface IFlyable with method Fly(). Create two classes Bird (with fields: name and canFly) and Plane (with fields: mark and highFly) , which implement interface IFlyable. Create List of IFlyable objects and add some Birds and Planes to it. Call Fly() method for every item from the list of it.

C# Collections .NET framework provides specialized classes for data storage and retrieval. There are two distinct collection types in C#: The standard collections from the System.Collections namespace The generic collections from System.Collections.Generic.  Generic collections are more flexible and safe, and are the preferred way to work with data.

ArrayList ArrayList is a special array that provides us with some functionality over and above that of the standard Array. Unlike arrays, an ArrayList can hold data of multiple data types. We can dynamically resize it by simply adding and removing elements.

Queue A Queue is a First-In-First-Out (FIFO) data structure. The first element added to the queue will be the first one to be removed. Queues may be used to process messages as they appear or serve customers as they come. Methods: Clear(); removes all elements from the Queue. Contains(object obj); determines whether an element is in the Queue. Dequeue(); removes and returns the object at the beginning of the Queue. Enqueue(object obj); adds an object to the end of the Queue. ToArray(); Copies the Queue to a new array.

Stack A stack is a Last-In-First-Out (LIFO) data structure. The last element added to the queue will be the first one to be removed. The C language uses a stack to store local data in a function. The stack is also used when implementing calculators.
