// Lab Optional 3:	Array parametrs to functions
// Date:			January 17, 2009
// 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.

	showNumbers(numbewr, SIZE);				//see array parameter number

	//get a word for charsOne
    cout<<" Enter a word of no more than 9 characters => "; 
	cin>>charsOne;							//here, we treat chars as a C-string
											//so that we can use cin to the charsOne
	cout<<"charOne is " <<charsOne <<endl;	//we can also use cout to output charsOne

	//get a word for charsTwo
	getChars(charsTwo, SIZE); 
	//output charsTwo

											//if you use "cout<<charsTwo<<endl;" see what will happen?

	/*************************************************************
	 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.
