The point of declaration for a name is immediately after its complete declarator (Clause [dcl.decl]) and before its initializer (if any), except as noted below. [ Example:
unsigned char x = 12;{ unsigned char x = x; }
Here the second x is initialized with its own (indeterminate) value. — end example ]
[ Note: a name from an outer scope remains visible up to the point of declaration of the name that hides it.[ Example:
const int i = 2;{ int i[i]; }
declares a block-scope array of two integers. — end example ] — end note ]
The point of declaration for an enumerator is immediately after its enumerator-definition.[ Example:
const int x = 12;{ enum { x = x }; }
Here, the enumerator x is initialized with the value of the constant x, namely 12. — end example ]
After the point of declaration of a class member, the member name can be looked up in the scope of its class. [ Note: this is true even if the class is an incomplete class. For example,
struct X {
enum E { z = 16 };
int b[X::z]; };
— end note ]
The point of declaration for an injected-class-name (Clause [class]) is immediately following the opening brace of the class definition.
The point of declaration for a function-local predefined variable ([dcl.fct.def]) is immediately before the function-body of a function definition.
The point of declaration for a template parameter is immediately after its complete template-parameter. [ Example:
typedef unsigned char T;
template<class T
= T , T N = 0> struct A { };
— end example ]
[ Note: Friend declarations refer to functions or classes that are members of the nearest enclosing namespace, but they do not introduce new names into that namespace ([namespace.memdef]). Function declarations at block scope and variable declarations with the extern specifier at block scope refer to declarations that are members of an enclosing namespace, but they do not introduce new names into that scope. — end note ]
[ Note: For point of instantiation of a template, see [temp.point]. — end note ]
