What do you mean by dynamic binding? How is it useful in OOP?
How does object-oriented approach differ from object-based approach?
List a few areas of application of OOP technology.
State whether the following statements are TRUE or FALSE:
In procedure-oriented programming, all data are shared by all functions.
The main emphasis of procedure-oriented programming is on algorithms rather than on data.
One of the striking features of object-oriented programming is the division of programs into objects that represent real-world entities.
Wrapping up of data of different types into a single unit is known as encapsulation.
One problem with OOP is that once a class is created it can never be changed.
Inheritance means the ability to reuse the data values of one object by another object.
Polymorphism is extensively used in implementing inheritance.
Object-oriented programs are executed much faster than conventional programs.
Object-oriented systems can scale up better from small to large.
Object-oriented approach cannot be used to create databases.
