Answer 1

16. Find the sum of negative elements of the array A(n,m)

Sub SumNegativeElements()

'Declare variables

Dim A(15, 15) As Integer

Dim sum As Integer

'Initialize array

For i = 0 To 14

For j = 0 To 14

A(i, j) = i + j

Next j

Next i

'Find sum of negative elements

sum = 0

For i = 0 To 14

For j = 0 To 14

If A(i, j) < 0 Then

sum = sum + A(i, j)

End If

Next j

Next i

'Print sum

Console.WriteLine("The sum of negative elements is: " & sum)

End Sub

17. Find the product of positive elements of the array A(n,m)

Sub ProductPositiveElements()

'Declare variables

Dim A(15, 15) As Integer

Dim product As Integer

'Initialize array

For i = 0 To 14

For j = 0 To 14

A(i, j) = i + j

Next j

Next i

'Find product of positive elements

product = 1

For i = 0 To 14

For j = 0 To 14

If A(i, j) > 0 Then

product = product * A(i, j)

End If

Next j

Next i

'Print product

Console.WriteLine("The product of positive elements is: " & product)

End Sub

18. Find the product of odd elements of the array A(n,m)

Sub ProductOddElements()

'Declare variables

Dim A(15, 15) As Integer

Dim product As Integer

'Initialize array

For i = 0 To 14

For j = 0 To 14

A(i, j) = i + j

Next j

Next i

'Find product of odd elements

product = 1

For i = 0 To 14

For j = 0 To 14

If A(i, j) Mod 2 <> 0 Then

product = product * A(i, j)

End If

Next j

Next i

'Print product

Console.WriteLine("The product of odd elements is: " & product)

End Sub

19. Find the arithmetic mean of all even elements of the array A(n,m) which are greater than K

Sub ArithmeticMeanEvenElements()

'Declare variables

Dim A(15, 15) As Integer

Dim mean As Double

Dim count As Integer

'Initialize array

For i = 0 To 14

For j = 0 To 14

A(i, j) = i + j

Next j

Next i

'Find arithmetic mean of even elements which are greater than K

mean = 0

count = 0

For i = 0 To 14

For j = 0 To 14

If A(i, j) Mod 2 = 0 And A(i, j) > K Then

mean = mean + A(i, j)

count = count + 1

End If

Next j

Next i

'If no even elements are greater than K, then print "No even elements found"

If count = 0 Then

Console.WriteLine("No even elements found")

Else

'Print arithmetic mean

Console.WriteLine("The arithmetic mean of even elements greater than K is: " & mean / count)

End If

End Sub

20. Find the sum of all negative elements of the array A(n,m) that are not divisible by K

Sub SumNegativeElementsNotDivisibleByK()

'Declare variables

Dim A(15, 15) As Integer

Dim sum As Integer

'Initialize array

For i = 0 To 14

For j = 0 To 14

A(i, j) = i + j

Next j

Next i

'Find sum of negative elements that are not divisible by K

sum = 0

For i = 0 To 14

For j = 0 To 14

If A(i, j) < 0 And A(i, j) Mod K <> 0 Then

sum = sum
