Question 1

A variable that has block scope can be used ____.&#10;A) within the procedure in which it is declared&#10;B) only within the statement block in which it is declared&#10;C) within any statement blocks in the program&#10;D) within any procedures in the program

Accepted Answer

A variable with block scope is only accessible within the block (or statement block) in which it is declared. It is not accessible outside of that block, even in the same procedure or other procedures in the program.

Question 2

In a dual-alternative selection structure, the word &#34;else&#34; to denote the beginning of the ____ path.&#10;A) true&#10;B) false&#10;C) correct&#10;D) wrong

Accepted Answer

The "else" keyword in a dual-alternative selection structure denotes the beginning of the false path, which is executed when the condition in the if statement evaluates to false.

Question 3

Variables declared within a statement block are referred to as ____ variables.&#10;A) global&#10;B) transient&#10;C) block-level&#10;D) internal

Accepted Answer

Variables declared within a statement block are referred to as block-level variables. They are only accessible within that block and are not visible outside of it. This helps with encapsulation and preventing naming conflicts with variables declared in other blocks or in the global scope.

Question 4

String comparisons in Visual Basic are case-sensitive.

Accepted Answer

String comparisons in Visual Basic are indeed case-sensitive. This means that "hello" and "Hello" are considered two different strings in VB.

Question 5

In Visual Basic, ____ is the not equal to operator.&#10;A) >>&#10;B) >=&#10;C)&#10;D)

Accepted Answer

In Visual Basic, the not equal to operator is represented by the symbol "<>". Therefore, the correct choice is D.

Question 6

You do not always need to include the ____ clause in an If ... Then ... Else statement.&#10;A) If&#10;B) Then&#10;C) Else&#10;D) End If

Accepted Answer

The Else clause is not always necessary in an If ... Then ... Else statement. The If and Then clauses are required to establish the condition and the action to be taken if the condition is true, but the Else clause is optional and only needs to be included if there is a specific action to be taken if the condition is false.

Question 7

You can divide by zero in Visual Basic with no problems.

Accepted Answer

Dividing any number by zero in Visual Basic (or any programming language) will result in a run-time error.

Question 8

If intQuantity >= 10 Then &#160;&#160;&#160;&#160; dblTotal = intQuantity * 2.5&#10;Else&#10;&#160;&#160;&#160;&#160; dblTotal = intQuantity * 3.5&#10;End If&#10;The intQuantity variable contains the number 8 before the code above is processed. What value will be in the dblTotal variable after the code is processed?&#10;A) 0&#10;B) 20&#10;C) 28&#10;D) 35

Accepted Answer

Since intQuantity is less than 10, the Else statement is executed, and dblTotal is assigned a value of 8 * 3.5, which is 28.

Question 9

In a single-alternative selection structure, the tasks to perform when the condition is true are called the ____ path.&#10;A) true&#10;B) right&#10;C) correct&#10;D) specific

Accepted Answer

In a single-alternative selection structure, the condition can only be true or false. If it is true, then the program will follow the path of code specified for true. Therefore, the tasks to perform when the condition is true are called the "true" path. The other choices (right, correct, specific) do not accurately describe the path.

Question 10

The set of statements contained in each path of the If...Then...Else statement is referred to as a(n) ____.&#10;A) statement clause&#10;B) operator block&#10;C) statement block&#10;D) comparison clause

Accepted Answer

The set of statements contained in each path of the If...Then...Else statement is referred to as a statement block. A statement block is a group of statements enclosed in curly braces that can be executed together as a single unit.
