100% Correct
You are writing a C# program and need to select an appropriate repetition structure
for your requirement. You need to make sure that the test for the termination condition
is performed at the bottom of the loop rather than at the top. Which repletion structure
should you use? - correct answer do-while statement
You are writing a C# program that needs to iterate a fixed number of times. You need
to make sure that your code is easy to understand and maintain even when the loop
body contains complex code. Which of the following C# statements provide the best
solution for this requirement? - correct answer for
You are developing code for a method that calculates the discount for the items sold.
You name the method CalculateDiscount. The method defines a variable, percentValue
,of the type double. You need to make sure that percentValue is accessible only within
the CalculateDiscount method. What access modifier should you use when defining the
percentValue variable? - correct answer private
You created a class named GeoShape. You defined a method called Area in the
GeoShape class. This method calculates the area of a geometric shape. You want the
derived classes of GeoShape to supersede this functionality to support the area
calculation of additional geometric shapes. When the method Area is invoked on a
GeoShape object, the area should be calculated based on the runtime type of the
GeoShape object. Which keyword should you use with the definition of the Area method
in the GeoShape class? - correct answer virtual
Suppose that you defined a class Scenario that defines functionality for running
customized pivot transform on large data sets. You do not want the functionality of this
,class to be inherited into derived classes. What keyword should you use to define the
Scenario class? - correct answer sealed
You need to provide printing functionality to several of your classes. Each class's
algorithm for printing will likely be different. Also, not all the classes have an "is-a"
relationship with each other. How should you support this functionality? - correct
answer Create a common interface that all classes implement
You are writing code for a class named Book. You should be able to get a list of all
books sorted by the author's last name. You need to write code to define this behavior
of a class. Which of the following class elements should you use? - correct answer
method
Suppose that you are writing code for a class named Product. You need to make sure
that the data members of the class are initialized to their correct values as soon as
, you create an object of the Product class. The initialization code should always be
executed. What should you do? - correct answer Create a constructor in the Product
class to initialize data members
You are developing a C# application. You create a class of the name Widget. You use
some third-party libraries, one of which also contains a class of the name Widget. You
need to make sure that using the Widget class in your code causes no ambiguity.
Which C# keyword should you use to address this requirement? - correct answer
namespace
You are developing a C# application. You need to decide whether to declare a class
member as static. Which of the following statements is true about static members of a
class? - correct answer The static keyword is used to declare members that do not
belong to individual objects but to a class itself
