A __________ is an association between an attribute and an entity, such as between a variable and its type or value, or between an operation and a symbol.

• the asterisk symbol (*) is usually bound to the multiplication operation at 1($).
• A data type, such as int in C, is bound to a range of possible values at 2($).
• A variable in a Java program is bound to a particular data type at 3($).
• A variable may be bound to a storage cell when the program is loaded into memory at 4($). That same binding does not happen until 5($) in some cases, as with variables declared in Java methods.
• A call to a library subprogram is bound to the subprogram code at 6($).

count = count + 5;

• The type of count is bound at 1($).
• The set of possible values of count is bound at compiler 2($).
• The meaning of the operator symbol + is bound at 3($), when the types of its operands have been determined.
• The internal representation of the literal 5 is bound at compiler 4($).
• The value of count is bound at 5($) with this statement
