How do you add a class in your C++ directory?

Question

I've been completing the exercises in a book to learn C++.

Exercise 1.20: http://www.informit.com/title/032174113 contains a copy of Sales_item.h in the Chapter 1 code directory. Copy that file to your working directory. Use it to write a program that reads a set of book sales transactions, writing each transaction to the standard output.

First off, the link they provided wasn't working. However, I got around this by finding the code on GitHub. However, I am extremely confused on how to add this to my directory. To be honest, I don't even know what that means? Could someone please explain how to add this code into your library?

Answer 1

id doesn't say "add to your directory", it says "copy that file to your working directory". Your working directory is the directory you put all your *.cpp and .h and project files in.

Answer 2

If it is what i'm thinking, do the following.

-Copy the Sales_item.h file to your working directory(probably where your code is) -Include the Sales_item.h file in your program using:

       #include "Sales_item.h"
