1. Object copy in container efficient, anti-stripping method: Make the container contain pointers instead of objects. （ps:stl containers are created in copy, compared to arrays, are dynamically created, saving time and space) 2. Always call empty ()

When we are programming, we sometimes use multithreading to solve problems, such as your program needs to process a lot of data in the background, but also to make the user interface operational, or your program needs to access some external
