Please use stacks in it. Please use c++. Thanks
Please use the attached header files for this
assignment. Don’t make any change to the name of the files or
functions. You just need to implement ProcessOrders.cpp based
on the three header files that you are given for this
assignment. You also must submit a cxxtest program similar to
the running examples to test your program. Use the examples
to verify your program works. But use different quantities
and cost values for the shipments or orders in your cxxtest program
when you submit the assignment.
