Results of the

 

 

 in conclusion:

 Global object initialization sequence and the opposite sequence destructor.

 May be performed in a data structure stack appreciated advanced after the first call initialization, after calling the destructor.

 Local object initialization sequence destructor, consistent with the global object.
