if your teacher or book doesn't require the above, they shouldn't be
teaching or be read.

aren't you reseting the private member auto_ptr?
why does the function signature indicate a return type and yet no
return is supplied?
try:
void CreateNew_PizzaProduct() { ... }
/*********** code getting crashed here ***************/
Your compiler should have detected the above anomaly, perhaps you need
to take a look at the compiler options. Thats off topic here.
