Question 1

A nested selection structure can appear within or immediately before the True path or the False path of the outer selection structure.

Accepted Answer

False

Question 2

Each Case clause represents a different ____.
A) method
B) program
C) path
D) partition

Accepted Answer

Each Case clause represents a different path. In programming languages such as Java and C++, a switch statement is used to evaluate a variable or expression and execute different pieces of code depending on the value of the variable or expression. Each case represents a path that the program can take based on the value of the variable or expression.

Question 3

Both paths in a selection structure can include instructions that declare variables, perform calculations, and so on.

Accepted Answer

Both paths in a selection structure can include instructions that declare variables, perform calculations, and any other valid instructions.

Question 4

A primary decision is always made by an outer selection structure, while a secondary decision is always made by a nested selection structure.

Accepted Answer

A primary decision is the first decision made in a program based on a condition, and it is made by an outer selection structure like an if statement. A secondary decision, which is made after the primary decision, is made by a nested selection structure like an if-else statement inside the primary decision.

Question 5

When either a selection structure's True path or its False path contains another selection structure, the inner selection structure is referred to as a ____.
A) truth table
B) nested selection structure
C) decision tree
D) decision plan

Accepted Answer

When a selection structure's True path or False path contains another selection structure, it is referred to as a nested selection structure or a nested if statement. The other options are not relevant or incorrect in this context.

Question 6

The expression 1 To 5 in the Case 1 To 5 clause specifies the range of numbers from ____.
A) 2 to 5, inclusive
B) 2 to 4, inclusive
C) 1 to 4, inclusive
D) 1 to 5, inclusive

Accepted Answer

The expression 1 To 5 specifies a range of numbers from 1 to 5 inclusive, so the correct choice is D.

Question 7

The Select Case statement ends with the ____ clause.
A) End Select
B) End
C) Finish
D) Stop Select

Accepted Answer

The Select Case statement always ends with the End Select clause to indicate that the block of code associated with the Select Case statement has ended.

Question 8

When using the Select Case statement, the data type of the ____ must be compatible with the data type of the selectorExpression.
A) Case expression
B) Case Else clause
C) instructions
D) expressions

Accepted Answer

The answer of When using the Select Case statement, the...

Question 9

If the Select Case statement includes a Case Else clause, the Case Else clause must be the ____ clause in the statement.
A) last
B) only
C) primary
D) secondary

Accepted Answer

The Case Else clause should be the last clause in the Select Case statement, following all of the specific Case clauses. This ensures that the program will first check all of the specific cases before resorting to the Else clause as a catch-all for any other input.

Question 10

You use the ____ keyword when you know only one end of a range (either the upper or lower end).
A) Is
B) All
C) To
D) From

Accepted Answer

The answer of You use the ____ keyword when you...

Question 11

When a multiple-alternative selection structure has many paths from which to choose, it is often simpler and clearer to use the If/ElseIf/Else form of the selection structure rather than the Select Case statement.

Accepted Answer

The Select Case statement is generally considered simpler and clearer when there are many paths from which to choose, as it organizes the conditions more neatly and is easier to read than multiple If/ElseIf/Else statements.

Question 12

You use the ____ keyword when you know both the upper and lower values in a range.
A) Is
B) All
C) To
D) From

Accepted Answer

The "To" keyword is used when defining a range and indicates the upper limit. For example, "Select * from table where age >= 18 and age <= 30" specifies a range of ages from 18 to 30 inclusive.

Question 13

The ____ in a flowchart represents the multiple-alternative selection structure's condition.
A) circle
B) diamond
C) square
D) triangle

Accepted Answer

The diamond shape in a flowchart represents the multiple-alternative selection structure's condition. It typically contains a yes/no question or a true/false condition that determines which path the program should take.

Question 14

An application may need to communicate with the user during run time.

Accepted Answer

An application may need to display information or ask for input from the user during run time.

Question 15

Each of the individual Case clauses, except the Case Else clause, must contain a(n) ____, which can include one or more expressions.
A) valueList
B) resultList
C) selectList
D) expressionList

Accepted Answer

The correct term is "expressionList." Each Case clause (except Case Else) in a Select Case statement must contain an expressionList, which can include one or more expressions to evaluate against the test expression.

Question 16

To include two groups of radio buttons in an interface, at least one of the groups must be placed within a ____, such as a group box, panel, or table layout panel.
A) Case
B) structure
C) container
D) statement

Accepted Answer

A container is used to group related controls together and manage their layout. In this case, a group box or panel can be used to contain the radio buttons and visually separate them from other controls on the interface. The other options (A, B, D) are not relevant to this scenario.

Question 17

A(n) ____ selection structure can choose from several alternatives.
A) open-ended
B) concurrent
C) dynamic
D) multiple-alternative

Accepted Answer

A multiple-alternative selection structure provides the programmer with the ability to choose from several alternatives based on the given conditions. This is the best choice since it accurately describes the scenario. The other options do not apply to this situation.

Question 18

A _____ decision is always made by an outer selection structure.
A) dynamic
B) static
C) primary
D) secondary

Accepted Answer

The answer of A _____ decision is always made by...

Question 19

In situations where the selection structure has many paths from which to choose, it is often simpler and clearer to code the selection structure using the ____ statement.
A) Select Case
B) Begin/End
C) If/Then
D) Do/Loop

Accepted Answer

The Select Case statement is best used in situations where there are many paths to choose from in a selection structure. It allows for easy readability and organization of code. The If/Then statement can become convoluted with too many nested structures, while the Do/Loop statement is not suitable for selection structures. The Begin/End statement is not a valid selection structure in most programming languages.

Question 20

A ____ decision is always made by a nested selection structure.
A) static
B) dynamic
C) primary
D) secondary

Accepted Answer

The answer of A ____ decision is always made by...
