From a Windows perspective, condition_variable resembles an event.The block waits for departure, but Condition_variable can start in bulk.The code is as follows://1111111.cpp: Defines the entry point of the console application.

There is a flaw in the simple factory model that violates the open and closed principle. The factory method mode avoids just one point.Opening and closing principle definition: A software entity should open for extension and close for modification.
