NEW QUESTION 9

A class named Manager is derived from a parent class named Employee. The Manager class includes characteristics that are unique to managers.
Which term is used to describe this object-oriented concept?

• A. inheritance
• B. data modeling
• C. data hiding
• D. encapsulation

Answer: A

Explanation:
Classes (but not structs) support the concept of inheritance. A class that derives from another class (the base class) automatically contains all the public, protected, and internal members of the base class except its constructors and destructors.
Incorrect:
not D: Encapsulation is sometimes referred to as the first pillar or principle of object- oriented programming. According to the principle of encapsulation, a class or struct can specify how accessible each of its members is to code outside of the class or struct. Methods and variables that are not intended to be used from outside of the class or assembly can be hidden to limit the potential for coding errors or malicious exploits.

NEW QUESTION 10

This question requires that you evaluate the underlined text to determine if it is correct.
Unit testing is the final set of tests that must be completed before a feature or product can be considered finished.
Select the correct answer if the underlined text does not make the statement correct. Select "No change is needed'' if the underlined text makes the statement correct.

• A. No change is needed
• B. User acceptance
• C. System
• D. Integration

Answer: B

Explanation:
User acceptance testing (UAT) is the last phase of the software testing process. During UAT, actual software users test the software to make sure it can handle required tasks in real-world scenarios, according to specifications.
UAT is one of the final and critical software project procedures that must occur before newly developed software is rolled out to the market.
UAT is also known as beta testing, application testing or end user testing.

NEW QUESTION 18

The Dog class and the Cat class inherit from the Animal class. The Animal class includes a breathe() method and a speak() method. If the speak() method is called from an object of type Dog, the result is a bark. If the speak() method is called from an object of type Cat, the result is a meow.
Which term is used to describe this object-oriented concept?

• A. multiple inheritance
• B. polymorphism
• C. data hiding
• D. encapsulation

Answer: A

Explanation:
Polymorphism is often referred to as the third pillar of object-oriented programming, after encapsulation and inheritance. Polymorphism is a Greek word that means "many-shaped" and it has two distinct aspects:
* At run time, objects of a derived class may be treated as objects of a base class in places
* such as method parameters and collections or arrays. When this occurs, the object's declared type is no longer identical to its run-time type.
* Base classes may define and implement virtual methods, and derived classes can override them, which means they provide their own definition and implementation. At run- time, when client code calls the method, the CLR looks up the run-time type of the object, and invokes that override of the virtual method. Thus in your source code you can call a method on a base class, and cause a derived class's version of the method to be executed.

NEW QUESTION 19

You run the following code:

What is the value of result when the code has completed?

• A. 10
• B. 20
• C. 30

Answer: B

Explanation:
The conditional-OR operator (||) performs a logical-OR of its bool operands. If the first operand evaluates to true, the second operand isn't evaluated. If the first operand
evaluates to false, the second operator determines whether the OR expression as a whole evaluates to true or false.
