(Account Information Application) Create an application that allows a user to
input a name, account number and deposit amount. The user then clicks the Enter
Button, which causes the name and account number to be copied and displayed in
two output Labels. The deposit amount entered will be added to the deposit amount
displayed in another output Label. The result is displayed in the same output Label.
Every time the Enter Button is clicked, the deposit amount entered is added to the
deposit amount displayed in the output Label, keeping a cumulative total.

{
label1.Text = textBox1.Text;
label2.Text = textBox2.Text;
