c++ - Passing in References vs. Pointers -

i getting error when pass in newtemp setemergencycontact(). error in regards to:

temp->contact::setemergencycontact(newtemp); 

"error: no matching function call 'contact::setemergencycontact(*&contact)'"

so question is: if have create object using pointer, how pass object function uses reference not pointer?

 contact generaterandomcontact(){         // name created         // generaterandomname() , phone number created         // generaterandomnumber(). using above random function,         // 50% probability assign new contact emergencycontact         // of 1 generated. otherwise leave null (default).         // return contact.  contact* temp = new contact; temp->contact::changename(generaterandomname()); temp->contact::changenumber(generaterandomnumber());     if(myrand(11) % 2 != 0){       contact* newtemp = new contact;       temp->contact::setemergencycontact(newtemp);    }  return *temp;   } 

emergency contact function:

void contact::setemergencycontact(contact & _emergencycontact){ contact* changeemergencys = new contact; changeemergencys = emergencycontact->getemergencycontact(); } 

dereference it:

temp->setemergencycontact(*newtemp)
