// This program is similar to static1.cpp, except that it does not declare the private
// variable "totalprice" as static. What difference did this change make?


// Key Points: 		1) "static" objects

#include "static2.h"

// The result of running the program:

 The total number of updates to the total price at this point is: 1

 The total number of updates to the total price at this point is: 2
 The price of v2 is: 10000 The total price of the vehicles at this point is: 10000

 The total number of updates to the total price at this point is: 3
 The price of v3 is: 30000 The total price of the vehicles at this point is: 30000
