            int myNumber=0;
            do
            {
                MessageBox.Show("number: " + myNumber,"do while loop");
                myNumber = myNumber + 1;
            } while (myNumber < int.Parse(TextBox1.Text));
        }

        private void Button2_Click(object sender, EventArgs e)
        {
            int myNumber = 0;
            while (myNumber < int.Parse(TextBox1.Text))
            {

                MessageBox.Show("number: " + myNumber, "while loop");
                myNumber = myNumber + 1;
            }
        }

        private void Button3_Click(object sender, EventArgs e)
        {

          int[] array1 = { 0, 1, 2, 3, 4, 5 };

          foreach (int n in array1)
          {
                MessageBox.Show("number: " + n, "foreach loop");            
           }
        }

        private void Button4_Click(object sender, EventArgs e)
        {
            for (int i = 0; i < int.Parse(TextBox1.Text); i++)
            MessageBox.Show("number: " + i, "for loop");            
        }
