Program Design

Here is a design for the program.

Get the starting balance 
'
Determine transaction type
'
IF deposit THEN
  Process a deposit. 
ELSE
  Process a check. 
END IF
Print the new balance. 
END

Now the details need to be filled in. A practical program would keep account information on your computer's hard disk and would go there to get the starting balance. But for this program the user will type in the starting balance. The program should prompt the user for this value.
