Repetition

1.            Compute the sum of the following series:

(a)  1+2+3+………. +N, where N is input and N > 1.

Dim i As Integer = 1

Dim output As Integer = 0

For i = 1 To TextBox1.Text

output = output + i

TextBox2.Text = output

Next i

End Sub

(b)  1+3+5+………..+ (2N+1), where N is input and N > 0.

Dim i As Integer = 1

Dim output As Integer = 0

Do While i <= 2 * TextBox1.Text + 1

output = output + i

i = i + 2

Loop

TextBox2.Text = output

End Sub

(c)   2+4+6+………..+ (2N), where N is input and N > 1.

Dim i As Integer = 2

Dim output As Integer = 0

Do While i <= 2 * TextBox1.Text

output = output + i

i = i + 2

Loop

MsgBox(output)

End Sub

(d)  5²+10²+15²+……. + (5N) ², where N is input and N > 1.

Dim s As Integer=0

Dim i As Integer=1

Dim m As Integer

Dim n As Integer

i=TextBox1.Text

n=TextBox1.Text

Do While i<=n

m=i*i

i=i+5

Loop

TextBox3.Text=s

End Sub

2.            Calculate the average of numbers within a range. (For example, average of numbers from 1 to 100). The range will be given as input.

     Dim i As Integer = TextBox1.Text

     Dim output As Integer = 0

     Do While i <= TextBox2.Text

     output = output + i

     i = i + 1

     Loop

     TextBox3.Text = output / TextBox2.Text

     End Sub

3.            Calculate the total number of evens or odds within a range of numbers (for example, the total number of evens or odds from 3 to 30). The range will be given as input.

          Dim i As Integer = TextBox1.Text

      Dim s As Integer = 0

      Dim a As Integer = 0

      For i = TextBox1.Text To TextBox2.Text

      If i Mod 2 = 0 Then

      s = s + 1

      Else

      a = a + 1

      End If

      Next i

      TextBox3.Text = s

      TextBox4.Text = a

      End Sub

4.            Calculate the factorial of a given number.

         

          Dim i As Integer = 1

      Dim output As Integer = 1

      Do While i <= TextBox1.Text

      output = output * i

      i = i + 1

      Loop

      TextBox2.Text = output

      End Sub

5.            Calculate the number of years to become a millionaire if a particular amount of money is deposited in a savings account and let it accumulate at a specific interest rate compounded annually.

         

        Dim a As Integer = TextBox1.Text

      Dim i As Integer = TextBox2.Text

      Dim c As Integer = 0

      Do While (a <= 100000)

      a = a + (a * i / 100)

      c = c + 1

      Loop

      TextBox3.Text = c

      End Sub

All Audio File Types

The Audio Files category includes compressed and uncompressed audio formats, which contain waveform data that can be played with audio playback software. This category also includes MIDI files, musical scores, and audio project files, which typically do not contain audio data. Common audio file extensions include .WAV, .AIF, .MP3, and .MID.
