Skeleton code template to help get started: orders_prog3.cpp

Here is a code example that may also help: jan31.cpp

Input file: PurchaseData.txt

Sample output: program 3 sample output.txt

Location ID changes for program 2 and program 3:

• 500 TAX rate is 4% (.04)
• 531 TAX rate is 6% (.06)
• 561 TAX rate is 6.6% (.066)
• 581 TAX rate is 7% (.07)
• locationID > 600 - TAX rate is 8.25% (.0825)
• is not a valid entry for the locationID (less than 500 is not valid)

here is a skeleton code
