JamEx Limited requires a program to calculate and print the commission received by a salesperson. The program should process an undetermined number of salespersons and appropriately terminate by a predefined input. The commission rate is based on two factors, the amount of sales and the class to which a salesperson belongs. The input will be the salesperson number, sales amount and class. The commission rate will be based on the following criteria:

Class=1 If sales is equal to or less than $1000, the rate is 6 percent. If sales is greater than $1000 but less than $2000, the rate is 7 percent. If the sales is $2000 or greater, the rate is 10 percent.

Class=2 If the sales is less than $1000, the rate is 4 percent. If the sales is $1000 or greater, the rate is 6 percent.

Class=3 The rate is 4.5 percent for all sales amount

Class=any other value Output an appropriate error message.
