// Lab 15:	value parameters vs. reference parameters
// Date:	January 12, 2009
// Comment: The code here is meant to be revised.
//
//-----------------------------------------------------------------
//
// This lab exercise is to show big difference between value parameters
// and reference parameters.
//
// Compile and run your program. When everything is fine,
// print your .cpp file and turn it to me or the TA.

	 Part B. Exercise. This part is for you to complete. 
	 Write two functions with reference parameters: 
	 (1) The first function "getNumber()" get two integers from the user. 
	 (2) The second function "larger()" takes two value parameter and one 
	 reference parameter and outputs the large of the two value 
	 parameter to the third reference parameter.
