#include <iostream>

//--------------------------------------------------------
// showDiff1.cpp
//
// Contract: main: void -> int
// Purpose: show that, without overloaded assignment
//          operator, assigning one object to another
//          really DOES make it reference the SAME
//          members when pointers are involved...
//          (AND copy-situations have the same effect)
//          [NOTE that this #include's Student1.h!]
//
// Examples: not really applicable --- simply shows
//           that, when [Student1.h's] Student s2 is 
//           assigned Student s1, changing one of s2's 
//           grades ALSO changes s1's corresponding grade, 
//           too!
