Listing
all of the places from which an identifier can be
|
|
|
accessed
legally is describing that identifier’s scope.

C++
defines several categories of scope for any identifier
|
|
|
|
– |
Class
scope. Postpone this until chapter 11.
|
|
|
|
– |
Local
scope. The scope of an identifier declared inside
|
|
|
a
block extends from the point of declaration to the end
|
|
|
of
that block.
|
|
|
|
– |
Global
scope. The scope of an identifier declared
|
|
|
outside
all functions and classes extends from the point
|
|
|
of
declaration to the end of the entire file containing the
|
|
program
code.
