// Lab 7:	Switch statement vs. if-else statement
// Date:	Januray 12, 2009
// Comment: The code here is meant to be revised.
//
//-----------------------------------------------------------------
//
// This lab exercise is to play with switch statements and to understand
// their equivalence to if-else statements
//
// Compile and run your program. When everything is fine,
// print your .cpp file and turn it to me or the TA.
