Hey I just got this book Accelerated c++ and it seems pretty good, but I'm having one problem in chapter 4. When I compile my grading program in chapter 4. I can't get the final version to work. I believe I'm supposed to enter a students name followed by grades, but I don't know how to create a condition that makes the first while loop stop, so I can show I'm done entering names and grades. I included the files that I'm working with. If you have the book they're the exact same.
