VB.net allows the (Implicit Conversion) in assignment statement if the value assigned in the right side is compatible with the data type of variable in the left side. ( )
Variables and constants cannot be used except in the scope of their declaration.( )
The function IsNumeric () is used to check if the value is numeric and returns true or not so it returns false. ( )
In (IF) statement the code that follows (Then) is executed when the result of the conditional expression is (False). ( )
Rem is the Keyword used to add comments inside the code window.( )
One of the ways to Prevent the Runtime Errors is using (Try….Catch) statement( )

------

Fourth : With the help of the code, complete the followings :

(For … Next ) Loop / (Do …. While ) Loop
Dim X , I As single
X = 4.5
For I = 0 To 7 Step 3
X = X * 2
Next

(A) This loop will be repeated for …………… times .

(B) The loop ends when ……………………………………………......

D)Rewrite the codes using DO …. While loop

Fifth : When this commands And keyword used:

command / usage
1 / IF…Then
2 / IF…Then… Else
3 / For…. Next
4 / Select …. case
5 / Do…While..Loop
6 / Function
7 / Sub
8 / Comparison Operators

Sixth : Consider the following code, which receives the user age entered in (TextBox1)and types and displays a quote according to the age.

Dim age As Byte

age = Me . TextBox1 . Text

Select Case age

Case 40

Label1 . Text = " Mature "

Case IS < 2

Label1 . Text = " Baby "

Case 2 To 10

Label1 . Text = " Child "

Case 12 To 19

Label1 . Text = " Teenager "

Case IS > = 20

Label1 . Text = " Adult "
