Question 5

VB.Net identifiers:
A)are case sensitive.
B)can begin with an underscore.
C)can begin with a number.
D)Both a and b.

Accepted Answer

VB.Net identifiers can indeed begin with an underscore, but they are not case sensitive and cannot begin with a number.

Question 6

The proper operator precedence, from first to last, is:
A)logical, comparison, and arithmetic.
B)arithmetic, comparison, and logical.
C)arithmetic, logical, and comparison.
D)comparison, arithmetic, and logical.

Accepted Answer

In most programming languages, the operator precedence is such that arithmetic operations are performed first, followed by comparison operations, and finally logical operations. This ensures that expressions are evaluated in a manner consistent with mathematical and logical norms.

Question 7

With A = False and B = True, which statement evaluates as True?
A)A AND A
B)A AND B
C)B AND A
D)B AND B

Accepted Answer

Given A = False and B = True, the only statement that evaluates as True is D) B AND B, because the AND operation requires both operands to be True for the result to be True. Since B is True, B AND B is True.

Question 8

Which operator is evaluated first?
A)NOT
B)AND
C)XOR
D)OR

Accepted Answer

The NOT operator is evaluated first according to the order of precedence in logical operations.

Question 9

In the For…Next statement the default value for the Step is:
A)-1
B)0
C)1
D)2

Accepted Answer

The default value for the Step in a For…Next loop is 1, which means the loop increments the counter variable by 1 in each iteration if no other Step value is specified.

Question 10

Which is a type of procedure found in VB.Net?
A)Event
B)Function
C)Sub
D)All of the above.

Accepted Answer

In VB.Net, all the options listed are types of procedures. Events are procedures that are triggered by actions in the application, Functions are procedures that return a value, and Subs are procedures that do not return a value.

Question 11

A sub procedure is valuable because it:
A)makes code easier to maintain.
B)splits the logic to solve a problem into small, manageable units.
C)limits the number of times the code can be accessed.
D)Both a and b.

Accepted Answer

Sub procedures make code easier to maintain and help split the logic into manageable units, but they do not limit the number of times the code can be accessed.

Question 12

Which method will return the number of elements in an array?
A)Dimension
B)Length
C)Number
D)Size

Accepted Answer

The correct method to return the number of elements in an array is "Length". This property is used in many programming languages like Java and C# to get the size of an array.

Question 13

What is required to reference an element in an array?
A)Array name
B)Index value of the element
C)Element value
D)Both a and b.

Accepted Answer

To reference an element in an array, both the array name and the index value of the element are required. The array name identifies which array you're working with, and the index specifies the position of the element within that array.

Question 14

Which method will arrange the elements of an array in alphabetical order?
A)Arrange
B)Assemble
C)Order
D)Sort

Accepted Answer

The sort method is used to arrange the elements of an array in alphabetical order (or any other order depending on the implementation).
