Q1: Is there a way I can have get_time() print out two different messages 
    for the first and second time?

A1: Not really.  But it does not need to.
  cout << "Enter first time (hr min sec). ";
  time1.get_time();
  cout << "Enter secound time(hr min sec). ";
  time2.get_time();
Q1: I'm getting:
 "p3.C", line 122: Error: Formal argument p of type char* in call to swap(char*,
 char*) is being passed char.
   Then later:
 "p3.C", line 122: Error: Formal argument p of type char* in call to swap(char*,
 char*) is being passed char**.

	Lets look at these message one at a time. Also remeber that the
header for swap is 
	void swap(char*p,char*q);

	Remeber that *p1 turns this in to the value of p1 or 
		*(char*) -> char
	So you are giving swap, which wants char*, char

	Rember that &p1 turns this into a pointer
		*(char*) -> char**
	So you are giving swap, which wants char*, char**
