interface in oops

What does an interface do?
Interfaces are useful for the following: Capturing similarities among unrelated classes without artificially forcing a class relationship.
Declaring methods that one or more classes are expected to implement.
Revealing an object's programming interface without revealing its class.
From an object-oriented programming perspective, the main difference between an interface and an abstract class is that an interface cannot have state, whereas the abstract class can have state with instance variables.

What is interface and example?

Methods form the object's interface with the outside world; the buttons on the front of your television set, for example, are the interface between you and the electrical wiring on the other side of its plastic casing.
You press the "power" button to turn the television on and off.

What is interface in OOP C++?

An interface describes the behavior or capabilities of a C++ class without committing to a particular implementation of that class.

In object-oriented programming, an interface or protocol type is a data type that acts as an abstraction of a class. It describes a set of method signatures, the implementations of which may be provided by multiple classes that are otherwise not necessarily related to each other.
