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

    • True

    • 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.

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

    • Is a dumb idea and a big waste of my time

    • Is not a part of a good programming practice

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

    • None of the above

    Correct Answer
    A. 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.

    Which one is NOT a development tool for iPhone/iPad applications?

    • The iPhone Simulator

    • Xcode

    • Interface Builder

    • SmallTalk-80

    Correct Answer
    A. SmallTalk-80
    Explanation
    SmallTalk-80 is not a development tool for iPhone/iPad applications. The iPhone Simulator, Xcode, and Interface Builder are all development tools that are commonly used for creating and testing applications for iPhone and iPad devices. SmallTalk-80, on the other hand, is a programming language and environment that is not specifically designed for iOS development.

    Standard to the iPhone/iPad is a device that allows the user to flip the screen from landscape to portrait mode simply by rotating the phone. By what name is this function better known? 

    • Nanometer

    • Rotating sensor

    • Proximity sensor

    • Accelerometer

    Correct Answer
    A. Accelerometer
    Explanation
    The correct answer is "Accelerometer." This is because an accelerometer is a device that measures the acceleration of an object. In the context of an iPhone or iPad, the accelerometer detects the orientation of the device and allows the user to rotate the screen from landscape to portrait mode by simply rotating the phone. The accelerometer senses the change in orientation and adjusts the display accordingly.

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

    • True

    • False

    Correct Answer
    A. 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.

    What is iPhone's screen resolution?

    • 240x320

    • 320x480

    • 480x960

    • 800x600

    Correct Answer
    A. 320x480
    Explanation
    The correct answer is 320x480. This is the resolution of the iPhone's screen, which refers to the number of pixels displayed horizontally and vertically on the screen. In this case, the iPhone's screen has a resolution of 320 pixels in width and 480 pixels in height.

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

    • Objects

    • Classes

    • Objects or classes

    • Objects and classes

    Correct Answer
    A. 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.

    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.

    • True

    • False

    Correct Answer
    A. 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.

    Besides being based on C, the Objective-C language was derived from a language called __?

    • Cocoa

    • SmallTalk-80

    • C

    • Xcode

    Correct Answer
    A. SmallTalk-80
    Explanation
    Objective-C was derived from a language called SmallTalk-80. This language heavily influenced the syntax and object-oriented features of Objective-C. SmallTalk-80 was a programming language and environment that was developed in the 1970s and 1980s. It was known for its simplicity and elegance, and it introduced many concepts that are still used in modern object-oriented programming languages. Objective-C took inspiration from SmallTalk-80 and added its own features, resulting in a powerful and flexible language that is widely used for developing macOS and iOS applications.

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

    • True

    • False

    Correct Answer
    A. 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.
