Not knowing C++, I'll use Ada terminology :-b
A program as a whole is executed. A program consists of declarations, statements
and expressions. Execution of each of these parts has a special name:
Declarations are elaborated.
Statements are executed.
Expressions are evaluate.
Thus a declarative part is elaborated, the following is done (in the sequence
defined in the RM):
Storage is allocated for the local variables, explicit or implicit initial
values are assigned to them, local tasks are started, etc...
Since initial values are expressions, all kinds of other program units may be
called. This is the infamous elaboration sequence problem when circularities are
detected.
