In C++, object construction and destruction can involve executing user code. Therefore, it is important to understand which initializations happen before entry to main and which destructors are invoked after exit from main. (For detailed information about construction and destruction of objects, see Constructors and Destructors in Chapter 11.)

The following initializations take place prior to entry to main:
