      Object Owned Programming

    • B.

      Object Ordered Programming

    • C.

      Object Oriented Programming

    Correct Answer

    Explanation
    The correct answer is Object Oriented Programming. Object Oriented Programming is a programming paradigm that organizes data and functions into reusable structures called objects. It emphasizes the use of objects, classes, and inheritance to create modular and maintainable code. OOP allows for encapsulation, polymorphism, and abstraction, which improve code readability and reusability.

    Rate this question:

  • 15. 

    Object Oriented Programming (OOP) is a style of programming in which your code is broken up into units, known as 

    • A.

      Objects

    • B.

      Classes

    • C.

      Objects or classes

    • D.

      Objects and classes

    Correct Answer
    D. Objects and classes
    Explanation
    In Object Oriented Programming (OOP), code is organized into units called objects and classes. Objects are instances of classes, which are blueprints or templates for creating objects. Classes define the properties (attributes) and behaviors (methods) that objects of that class can have. By breaking up code into objects and classes, OOP allows for modular and reusable code, making it easier to manage and maintain large programs.

    Rate this question:

  • 16. 

    Keeping track of objects you own and releasing them when you're done using them

    • A.

      Is a dumb idea and a big waste of my time

    • B.

      Is not a part of a good programming practice

    • C.

      Is necessary on the iPhone since it does not support garbage collection

    • D.

      None of the above

    Correct Answer
    C. Is necessary on the iPhone since it does not support garbage collection
    Explanation
    The correct answer is that keeping track of objects you own and releasing them when you're done using them is necessary on the iPhone since it does not support garbage collection. This means that on the iPhone, the responsibility of managing memory and releasing objects falls on the programmer, as the device does not automatically handle garbage collection. This is an important aspect of programming on the iPhone and is considered a good practice to prevent memory leaks and optimize performance.

  • 17. 

    At the start of program execution all subclasses are initialized before the parent class 

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    The statement is false because in Java, the parent class is always initialized before the subclasses. This is because the subclasses inherit properties and methods from the parent class, so the parent class needs to be fully initialized before the subclasses can access and use its members.

    Rate this question:

  • 18. 

    The @private directive restricts access to instance variables to methods in the class; subclasses cannot access the variables directly

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    The @private directive in a class restricts access to its instance variables, allowing only methods within the class to access them. Subclasses, which inherit the properties and methods of the parent class, cannot directly access these variables. Therefore, the statement "The @private directive restricts access to instance variables to methods in the class; subclasses cannot access the variables directly" is true.

    Rate this question:

  • 19. 

    If you start a class definition that conforms to a specified protocol, you need to release all the methods you will implement for that protocol in the @interface section.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    In Objective-C, when starting a class definition that conforms to a specified protocol, you do not need to release all the methods you will implement for that protocol in the @interface section. The @interface section is used to declare the methods and properties of the class, while the actual implementation of the methods is done in the @implementation section. Therefore, it is not necessary to release the methods in the @interface section.

    Rate this question:

  • 20. 

    int, float, and char are reserved words and examples of Objective-C basic objects.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    The statement is false because int, float, and char are not reserved words in Objective-C. They are actually data types used to declare variables in the language. Reserved words in Objective-C include keywords like if, else, for, while, etc.
