// This program gives an introduction to exceptions and exception handling.
// Exceptions are run-time program anomalies such as division by zero, 
// arithmetic or array overflow, the exhaustion of free store, ..etc.   
// In specific the program introduces "assert". An assert statement is 
// placed in a program to insure that some condition will never occur. 
// If this condition occurs, then the program will immediately terminate.
// Notice that this is not the best way to handle an exception. Why?

// Key Points:		1) assert


#include <iostream.h>
#include <assert.h>
