Answer

Fundamental principles of object-oriented programming languages are:

• abstraction - allows abstracting from the actual manipulation of data/objects/code and synthesize it into instructions of business logic.
• encapsulation - data and methods are encapsulated into containers.
• inheritance - objects may inherit properties from another object.
• polymorphism - objects may dynamically adapt themselves to another container.

Structured programming languages are function or procedure -oriented - they is why sometimes they are called procedural programming languages. Structured programming languages are used the data given through parameters of functions or procedures (for instance - f(d) ), while in object-oriented programming languages, the methods(functions) are attached to the object(data) (for instance - d.f() ).
