// Lab 9:	Play with iterator methods for a class (or container)
//			via the implementation of vector class template
// Date:	January 14, 2009
// Comment: The code here is meant to be revised.
//
//-----------------------------------------------------------------
//
// This lab exercise is practice iterator method for a class (or container). 
// An interator is just like a pointer to the class object, which can move via 
// address operations such as ++ and --, access the content pointed to by it via
// dereference operator *, and do comparisons, etc. With with help of interator 
// method, it is inconvenient to move around a "list" of objects and to do insertion, 
// deletion operatioms, etc. 
//
// Compile and run your program. When everything is fine,
// print your .cpp and .h files and turn them to me or the TA.
