Answer:
4) 3 11 44
Explanation:
Given data
int [] val = { 3, 10, 44 };
The total number of parameters of given array are 3, so total length of array is also 3.
The indexing of array starts with '0', Therefore the indexes of array with length zero are: {0,1,2}
The value of array at index 0 is = 3
similarly,
value at index 1 = 10
value at index 2 = 44
Here, Int i = 1 is storing the value '1' in integer variable i.
In addition to that, any value of index 'i' of an array is selected using array[i].
Therefore,
val[i] is selecting the value of array located at index '1' because i = 1.
val[i] = val[1] = 10
val[i]+1 is selecting the value of array located at index 'i' that is (1) and adding 1 to it
=> val[i] = 10
=> val[i]+1 = 10+1 = 11
Finally,
val[i] = val[i]+1; is copying the val[i]+1 = 11 to value placed at index 1 (10). Hence, the output would be {3 11 44}. So 4th option is correct.

Answer: Reverse DNS zone
Explo: a reverse DNS zone needs a PTR record since it is in charge of resolving the IP address to a domain or a hostname.
Answer:
Public Class Form1
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
Dim sum, product, num1, num2 As Integer
num1 = Val(TextBox1.Text)
num2 = Val(TextBox2.Text)
sum = num1 + num2
product = num1 * num2
TextBox3.Text = sum
TextBox4.Text = product
End Sub
End Class
- Explanation:
- The solution is implemented in Visual Basic Programming Language
- Two textboxes are created to receive the user's input and two textboxes for displaying sum and product respectively
- Each of these controls are appropriately labeled (See the attached GUI interface)
- The Sum is calculated by adding the values from textbox1 and 2
- The product is calculated by multiplying both
