C# was designed by Microsoft as an object-oriented and component-oriented language to support modern software development practices.

Question 5

What technique involves the packaging of an object's attributes and methods into a cohesive unit that can be used as an undivided entity?
A) encapsulation
B) polymorphism
C) inheritance
D) interface

Accepted Answer

Encapsulation is the technique of bundling the data (attributes) and methods (functions) that operate on the data into a single unit or class, restricting access to some of the object's components.

Question 6

The Visual Studio IDE gives you advanced features such as syntax coloring and automatic statement completion.

Accepted Answer

Visual Studio IDE provides advanced features like syntax coloring and automatic statement completion to enhance coding efficiency and accuracy.

Question 7

What information must be supplied when utilizing a method that requires additional information in order to operate?
A) literal strings
B) primitive data
C) arguments
D) namespace

Accepted Answer

Arguments are the additional information supplied to a method to enable it to perform its task.

Question 8

What term describes a one-word name with no embedded spaces that references a variable in a program?
A) behavior
B) bug
C) identifier
D) attribute

Accepted Answer

An identifier is a one-word name used in programming to reference a variable, function, or other entities, and it does not contain spaces.

Question 9

What is the process of removing all syntax and logical errors from a program in order to create a working program that accomplishes all intended tasks known as?
A) debugging
B) compiling
C) commenting out
D) executing

Accepted Answer

Debugging is the process of identifying and removing syntax and logical errors from a program to ensure it functions correctly and accomplishes all intended tasks.

Question 10

When the keyword void is used in the Main() method header, it indicates that the Main() method is empty.

Accepted Answer

The keyword "void" in the Main() method header indicates that the method does not return a value, not that it is empty.

Question 11

What type of program is created by the use of named memory locations and a series of steps or operations to manipulate the values of those memory locations?
A) object-oriented
B) component-oriented
C) variable-oriented
D) procedural

Accepted Answer

Procedural programming involves using named memory locations (variables) and a series of steps or operations (procedures or functions) to manipulate those values, focusing on the sequence of actions to be performed.

Question 12

Machine language is expressed as a series of 1s and 0s.

Accepted Answer

Machine language, also known as machine code, is the lowest-level programming language and is composed of binary code, which is represented by sequences of 1s and 0s.

Question 13

Encapsulation is similar to using a device without regard for the internal mechanisms.What is the common term for this type of device?
A) interface
B) black box
C) object
D) blue box

Accepted Answer

Encapsulation is often compared to a "black box" because it allows users to interact with an object without needing to understand its internal workings, similar to how a black box operates.

Question 14

What kind of programming language allows you to use a vocabulary of reasonable terms such as "read," "write," or "add" instead of the sequence of on/off switches that perform these tasks?
A) high-level
B) machine-level
C) low-level
D) switch-level

Accepted Answer

High-level programming languages use human-readable terms like "read," "write," or "add," making them easier to understand and use compared to machine-level or low-level languages, which are closer to binary code.

Question 15

What programming style capitalizes the first letter of all new words in an identifier, including the first one?
A) camel casing
B) upper casing
C) OOP casing
D) Pascal casing

Accepted Answer

Pascal casing capitalizes the first letter of all words in an identifier, including the first one.

Question 16

What can be used to extend an existing class so as to create a more specific class?
A) inheritance
B) encapsulation
C) polymorphism
D) abstraction

Accepted Answer

Inheritance is the process of creating a new class that inherits the properties and methods of an existing class. This allows you to create more specific classes that can be used to represent different types of objects.

Question 17

A series of four or five comparisons and calculations that together determine an employee's withholding tax value might be grouped using what sort of logical unit?
A) an attribute
B) a method
C) a class
D) a structure

Accepted Answer

A method is a logical unit in programming that can perform a series of operations, such as comparisons and calculations, to determine a value like an employee's withholding tax.

Question 18

A program's execution of various statements and procedures in a correct order to produce desired results is referred to as what defining characteristic?
A) the program's GUI
B) the attributes utilized by the program
C) the methods of the program
D) the program's logic

Accepted Answer

The program's logic refers to the sequence and control flow of statements and procedures that ensure the program executes correctly to achieve the desired results.

Question 19

What is an object in relation to a defined class in a programming language?
A) It is a property of the class.
B) It is an interface to the class.
C) It is an instance of the class.
D) It defines the class state.

Accepted Answer

An object is an instance of a class, meaning it is a concrete realization of the class blueprint, containing specific data and behavior as defined by the class.

Question 20

C# programmers must use Pascal casing when creating method names to produce an executable program.

Accepted Answer

Pascal casing is a convention, not a requirement, for method names in C#. It is recommended for readability and consistency, but not mandatory for program execution.
