// The Mortgage class contains fields for mortgage

// number, customer name, price of house, down

// payment, mortgage amount, and mortgage rate,

// and methods to set and get the values.

// The mortgage number must be betwen 10000 and 59999 inclusive

// or else it is set to 0

// The down payemnt cannot be more than the price of the house

// If it is, an error message is displayed

// and the down payment is reduced

// The mortage amount is the difference between the house price

// and the down payment

// The mortgage rate differs for loans of different sizes

// Loans over $200,000 get a preferred rate

// The demonstration program instantiates three Mortgages and

// purposely assigns invalid values to some of the arguments;

// the class methods will correct the invalid values.
