Hi

AFAIK it is common practice to use pointers instead of references when a 
functions needs to change some of its parameters, the reason is the one 
pointed out by Jason:
when a routine requires a reference parameter, the user may not think that 
it will be modified, on the other hand passing a pointer (of course non 
const) stresses the fact that the parameter will be changed.

To make it clearer, one should use: "void swap(int *pa, int *pb);"
instead of "void swap (int &a, int &b);"

Of course there are cases when you are forced to use references: 
overloading the stream insertion operator (">>")is one of these; more 
often, for efficiency reasons, one finds some parameter passed as a const 
referece: this is safe because of the const.
