Programming Assignment DUE Date: See vour Blackboard Classes & Inheritance Project 5 will create a class that will be used in Project 6, so Project 6 is dependent on you completing Project 5 successfully. Project 6 will explore how inheritance works in C++ by defining our own small inheritance tree. We will start with defining a base class in this project and then build on it in our next project. Objective:s Implementing a class Using a header file Using the . class to 'build' up output strings Using stringstreanm To get full credit for this assignment, you need to use the stringstream object to build the string returned in the toString accessor. You can think of a string stream as a bunch of characters floating down a stream sequentially where they all stack up at a dam. They aren't a string yet, they're still in the 'stream'. You then need to convert the stringstream into a string, which can then be returned from the toString accessor to the caller. To use the stringstream object you need to include 'sstream' into your program. For background on how to use the stringstream object you can start here htsstream/stringstream/stringstream/ tp://www.cplusplus.com/reference/ Don't forget to convert the stream to a string (you'll need to do a little digging (googling) Tasks For this project you are going to create a class that represents a manufactured 'Part' on a bill of material (BOM). This Part will have the following attributes (represented as a private variable) identifier - The parts identifier as an alpha numeric string drawing - The AutoCAD drawing file that represents the part quantity - The number of parts that are required
