Question 1

Variables declared using a structure are often referred to as ____.
A) functions
B) Subs
C) structure variables
D) objects

Accepted Answer

Variables declared using a structure are commonly referred to as structure variables. Functions and subs are typically used to define and execute a block of code, while objects are instances of a class in object-oriented programming.

B) StreamReader object
C) StreamWriter object
D) AppendText method

Accepted Answer

A

Question 3

Accepted Answer

Files to which information is written are called output files. Input files are those from which information is read or retrieved.

Question 4

Programmers refer to a sequence of characters as a ____.
A) string of characters
B) stream of characters
C) file
D) variable

Accepted Answer

The answer of Programmers refer to a sequence of characters...

Question 5

You cannot include an array in a structure.

Accepted Answer

Arrays can be included as a member of a structure in many programming languages like C, C++, and Java.

Question 6

The syntax used to declare a StreamWriter variable is ____.
A) {Dim|Private} streamWriterVariableName IO.StreamWriter
B) {Dim|Private} streamWriterVariableName As IN.StreamWriter
C) {Dim|Private} streamWriterVariableName As IO.StreamWriter
D) {Dim|Private} streamWriterVariableName As StreamWriter

Accepted Answer

The correct syntax to declare a StreamWriter variable is the option C: {Dim|Private} streamWriterVariableName As IO.StreamWriter. It begins with either "Dim" or "Private," followed by the name of the variable, and then the keyword "As" with the data type. In this case, the data type is IO.StreamWriter, as StreamWriter is a part of the IO (Input/Output) namespace.

Question 7

Data types created using the Structure statement are referred to as user-defined data types or structures.

Accepted Answer

Structures allow programmers to create their own custom data types, which are referred to as user-defined data types.

Question 8

The Peek method, looks ahead into the file to determine whether the file contains another character to read.

Accepted Answer

The Peek method allows us to look at the next character in the file without actually reading it. This is useful when we want to determine if there are more characters to read, without moving the file position pointer forward.

Question 9

You use the ____ member access operator to separate the structure variable's name from the member variable's name.
A) ()
B) arrow
C) asterisk
D) dot

Accepted Answer

The dot member access operator is used to separate the structure variable's name from the member variable's name. The arrow operator is used when accessing members of pointer to a structure. The asterisk is used to define a pointer variable. The parentheses are used for function calls and expressions.

Question 10

You reserve memory locations by declaring a structure variable.

Accepted Answer

When a structure variable is declared, memory is reserved for all the members of the structure.

Question 11

In Visual Basic, you use a(n) ____ to write a stream of characters to a sequential access file.
A) CreateText method
B) StreamReader object
C) StreamWriter object
D) AppendText method

Accepted Answer

To write a stream of characters to a sequential access file, you use a StreamWriter object in Visual Basic. The CreateText method is used to create a new file, AppendText method is used to append text to an existing file, and the StreamReader object is used to read from a file.

Question 12

In addition to getting data from the keyboard and sending data to the computer screen, an application can also get data from and send data to a file on a disk.

Accepted Answer

This is true. Applications can read data from and write data to files on a disk. This is a common way to store and retrieve information even after the application has closed.

Question 13

The members of a structure can be variables, constants, or ____.
A) structures
B) classes
C) procedures
D) control characters

Accepted Answer

The answer of The members of a structure can be...

Question 14

To access a member of a structure variable in an array, you use the syntax ____.
A) arrayName ( subscript ). memberVariableName
B) arrayName ( subscript )-> memberVariableName
C) arrayName ( subscript )[ memberName ]
D) arrayName ( subscript )@ memberName

Accepted Answer

The correct syntax to access a member of a structure variable in an array is by using the dot operator (.) after specifying the array element through its subscript, as in "arrayName(subscript).memberVariableName". This syntax is used when dealing with arrays of structures in languages like C and C++.

Question 15

Files that are read by the computer are called ____ files.
A) storage
B) serial
C) input
D) report

Accepted Answer

Files that are read by the computer are known as input files, as they are fed into the computer for processing. Choices A, B, and D do not accurately describe files that are read by the computer. "Storage" files could refer to any type of file stored on a computer, "serial" pertains to the manner in which data is transmitted, and "report" typically refers to an output file generated by the computer, not an input file.

Question 16

Most programmers use the Structure statement, rather than the Class statement, to create data types that contain procedures.

Accepted Answer

Most programmers use the Class statement to create data types that contain procedures in Object-Oriented Programming. The Structure statement is used to create simple data types with no methods.

Question 17

A file to which information is written is referred to as a(n) ____ file.
A) report
B) text
C) output
D) data

Accepted Answer

An output file is the term used to describe a file that is designed to receive data written to it by a program or process. This contrasts with an input file, which is read by the program.

Question 18

Programmers use structure variables to store related items in an array, even when the items have different data types.

Accepted Answer

This is true, as a structure variable can contain different data types within the same array.

Question 19

When you pass a structure variable to a Sub or Function procedure, its member variables are not automatically passed.

Accepted Answer

When you pass a structure variable to a Sub or Function procedure in languages like VB.NET or C#, the entire structure, including all its member variables, is passed to the procedure.

Question 20

You can use the Strings.Space method to include a specific number of space characters in a string.

Accepted Answer

The Strings.Space method can be used to include a specific number of space characters in a string, such as "Hello" + Strings.Space(4) + "World" to create the string "Hello    World" with four spaces in between.
