You can't return info from a void function.  "void" means that it doesn't 
return anything.  If you want data to use you change it so that it has an 
apropriate type.  However the fuctions as they are now read form standard 
input, and wrire to standard output so for the time being leave them as they 
are.  

I suggest you don't worry about this yet.  First get the object working then 
worry about what you are going to do with them.  You will get further doing 
this in lots of little steps rather than trying to solve all the world 
problems all at onece.
