// Lab Optional 3:	Array parametrs to functions
// Date:			January 17, 2009
// Revised on:		06/30/2009 by SIRISHA SURISETTY
// Comment:			The code here is meant to be revised.
//
//---------------------------------------------------------------------
//
// This lab exercise is to show how array parameters to functions work.
//
// Compile and run your program. When everything is fine,
// print your .cpp and .h files and turn them to me or the TA.

	/*************************************************************
	 This part is for you: 
	 (1) Write a function to convert all letters in a char array to lower case 
		 and then call this function for convert array charsOne. 
	 (2) Write a function to reverse letters in an char array and then call 
	     this function to convert the array charsTwo.
