For each of the following Visual Basic code snippets, identify the syntax error.
1. If intX > 100
lblResult. Text = "Invalid Data"
End If
2. Dim str As String = "Hello"
Dim intLength As Integer
intLength = Length(str)
3. If intZ < 10 Then
lblResult. Text = "Invalid Data"
4. Dim str As String = "123"
If str. IsNumeric Then
lblResult. Text = "It is a number."
End If
5. Select Case intX
Case < 0
lblResult. Text = "Value too low."
Case > 100
lblResult. Text = "Value too high."
Case Else
lblResult. Text = "Value just right."
End Select

1. No 'Then' in the if statement

2. No syntax error.

3. No closing if statement that is no "END IF"

4. No syntax error

5. No syntax error

Explanation:

1. The syntax for writing if statement in visual basic is:

If condition Then

'Stament block'

End If

From the above syntax, we see that the "Then" keyword is missing in the snippet.

2. This is okay as there is no syntax error.

str was declared as a string and a variable was assigned to it. Then, intLength was also declared as integer and the length of str is assigned to it.

3. The syntax for writing if statement in visual basic is:

If condition Then

'Stament block'

End If

From the above we can see that "End If" is missing in the given snippet.

4. There is no syntax error. The opening if and ending if are present.

5. There is no syntax error. The general form of writing a select case statement in Visual basic is:

Select Case VariableName

Case 1

"Statement to execute"

Case 2

"Statement to execute"

Case Else

"Default Statement to execute if other case fail"

End Select

1. a

2. a

3. d
