	Purpose: Print entered check and checking account information
		     with formatted output to a file
	Algorithm: Ask user for checking account balance, then ask repeatedly
	           for check information until user enters 0 as check number
*/

	//least once, so that user can enter 0 as first check number to terminate loop
