Question
Type a single Visual Basic statement that declares myHeight as a real number and initializes it to 6.15. Note: Letters that are not capitalized properly will count against you (e.g., the following statement is incorrect: dim temp as double). Make sure to only include one space in between each word/letter/symbol.
Type a single Visual Basic statement that declares myWeek as a whole number and initializes it to 3. Note: Letters that are not capitalized properly will count against you (e.g., the following statement is incorrect: dim temp as double). Make sure to only include one space in between each word/letter/symbol.
Type a single Visual Basic statement that declares myWeight as a real number and initializes it to 131.55. Note: Letters that are not capitalized properly will count against you (e.g., the following statement is incorrect: dim temp as double). Make sure to only include one space in between each word/letter/symbol.
Type a single Visual Basic statement that declares variable health as a whole number and initializes it to 100. Note: Letters that are not capitalized properly will count against you (e.g., the following statement is incorrect: dim temp as double). Make sure to only include one space in between each word/letter/symbol.

Explanation / Answer
In Visual Basic the variables are declared using Dim keyword.
Syntax:
Dim variableName As VariableType
1.
Dim myHeight As Double = 6.15
Explanation:
Double (double-precision floating point) allocates 8 bytes of memory for real numbers.
2.
Dim myWeek As Integer = 3
Explanation:
Integers are whole numbers, but they also include negative numbers, but still no fractions allowed.
Therefore, integers can be negative {-1, -2,-3, -4, -5, ... }, positive {1, 2, 3, 4, 5, ... }, or zero {0}
We can put that all together like this:
Integers = { ..., -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, ... }
3.
Dim myWeight As Double = 131.55
Explanation:
Double (double-precision floating point) allocates 8 bytes of memory for real numbers.
4.
Dim health As Integer = 100
Explanation:
Integers are whole numbers, but they also include negative numbers, but still no fractions allowed.
Therefore, integers can be negative {-1, -2,-3, -4, -5, ... }, positive {1, 2, 3, 4, 5, ... }, or zero {0}
We can put that all together like this:

5.
Dim myPar As Integer = 10
Explanation:
Syntax:
Dim variableName As VariableType=value
Hence, the correct option is B.
6.
True
Explanation:
Dim variableName As VariableType
Dim myPar As Double
7.
True
Explanation:
Dim variableName As VariableType
Dim myNum As Integer
8.
False
Explanation:
Dim variableName As VariableType
Dim myData As Double
