Local constant declarations
A local-constant-declaration declares one or more local constants. local-constant-declaration: constant-declarators: constant-declarator: The type of a local-constant-declaration specifies the type of the constants introduced by the declaration. The type is followed by a list of constant-declarators, each of which introduces a new constant. A constant-declarator consists of an identifier that names the constant, followed by an “=” token, followed by a constant-expression (§7.19) that gives the value of the constant. The type and constant-expression of a local constant declaration must follow the same rules as those of a constant member declaration (§10.4). The value of a local constant is obtained in an expression using a simple-name (§7.6.2). The scope of a local constant is the block in which the declaration occurs. It is an error to refer to a local constant in a textual position that precedes its constant-declarator. Within the scope of a local constant, it is a compile-time error to declare another local variable or constant with the same name. A local constant declaration that declares multiple constants is equivalent to multiple declarations of single constants with the same type.
