The document discusses two Visual Basic programs: 1. A program that calculates exponents by inputting a number and power and uses a for loop to calculate the result. 2. A program that calculates the sum of numbers within a range input by the user using a for loop to iterate from the start to end number. Both programs utilize buttons to run the calculations, clear fields, and close/open additional forms.

2. PROGRAM PANGKAT

3. Source Code:
Private Sub Button2_Click(ByVal sender As
System.Object, ByVal e As System.EventArgs)
Handles Button2.Click
TextBox1.Clear()
TextBox2.Clear()
TextBox3.Clear()
TextBox1.Focus()
End Sub
Private Sub Button3_Click(ByVal sender As
System.Object, ByVal e As System.EventArgs)
Handles Button3.Click
Close()
End Sub
Private Sub Button1_Click(ByVal sender As
System.Object, ByVal e As System.EventArgs)
Handles Button1.Click
Dim nilai As Integer
Dim pangkat As Integer
Dim i As Integer
Dim jumlah As Integer
nilai = Val(TextBox1.Text)
pangkat = Val(TextBox2.Text)
jumlah = 1
For i = 1 To pangkat
jumlah = jumlah * nilai
Next
TextBox3.Text = jumlah
End Sub
Private Sub Button4_Click(ByVal sender As
System.Object, ByVal e As System.EventArgs)
Handles Button4.Click
Form1.Show()
End Sub
End Class

4. PROGRAM PERULANGAN PENJ

5. PENJELASAN:
AWAL: 1
AKHIR: 5
HASIL: 15
Nilai awal+Nilai akhir tetapi secara
perulangan
Artinya 1+2+3+4+5 = 15

6. Source Code:
Private Sub Button3_Click(ByVal sender As
System.Object, ByVal e As System.EventArgs)
Handles Button3.Click
Close()
End Sub
Private Sub Button2_Click(ByVal sender As
System.Object, ByVal e As System.EventArgs)
Handles Button2.Click
TextBox1.Clear()
TextBox2.Clear()
TextBox3.Clear()
TextBox1.Focus()
End Sub
Private Sub Button1_Click(ByVal sender As
System.Object, ByVal e As System.EventArgs)
Handles Button1.Click
Dim jumlah As Integer
Dim awal As Integer
Dim akhir As Integer
Dim i As Integer
awal = Val(TextBox1.Text)
akhir = Val(TextBox2.Text)
For i = awal To akhir
jumlah = jumlah + i
Next
TextBox3.Text = jumlah
End Sub
Private Sub Button4_Click(ByVal sender As
System.Object, ByVal e As System.EventArgs)
Handles Button4.Click
Form2.Show()
End Sub
End Class
