本文探讨了C++中不同类型的变量存储期限，包括使用new分配的对象必须用delete释放的动态存储期限，全局变量的静态存储期限，以及局部变量的自动存储期限。
The core idea is: objects allocated with new must be deallocated with
delete. These are said to have "dynamic storage duration."
Global variables have "static storage duration" and exist for the lifetime of the program.
Other variables (mainly function local variables, object members) have "automatic storage duration." These are destroyed, and their space reclaimed, when they go out of scope, and only then.
