[snipped rest of code]

There you go. Why did you include <string.h> when you want to use <string>. 
That is a big deal difference. <string.h> is the header for C-style strings 
whereas <string> is just the thing you are trying to get.
If you want to know about all the functions in there, you will have to take a 
look at it. But I guess your book will do just fine.
