How to solve the ARRAY Problem...

CKShia (8)
Salesperson at McHenry Tool corporation are given a monthly commission check. Use array method to compute a salesperson’s monthly commission for several number of salesperson.

Input =
1. name of the salesperson
2. commission rate
3. gross monthly sales

Commission = gross monthly sales * commission rate.

The output should be arranged in the way so that each salesperson’s commission should be printed next to his or her name.

Output =
1. Total monthly commission (summed across all salespersons)
2. The average commission per salesperson

Error Checking: Any names of sales persons who have invalid data should be printed out separately. Data are invalid if the commission rate is not between 0.01 and 0.50 or if the gross monthly sales figure is negative.


This is my coding......
