// Introduction to Computer Programming I
//
// Details: The program evaluates the information put in and seperates, in the report, the 
//          product character, the class caracter, the amount, the distance, the cost of 
//          materials, the cost of delivery, sales tax, and total amount per person. It 
//          also tells us the number of orders and the number of orders each product. It also
//          tell the minimum amount, maximum amount, and the total amount recorded 
//          through that report.
