The star indicates that it is a pointer.
int *rTemp
is a pointer to an integer. If you are not familiar with pointers then you should read about them in your text book. There are also several tutorials on the net.

Your text book and/or your tutor should always be your first point of call for these types of questions; If you need more information, then have a look at these links:
