C标准里提到：The name "lvalue" comes originally from the assignment expression E1 = E2, in which the left operand E1 is required to

be a (modifiable) lvalue. It is perhaps better considered as representing an object "locator value". What is sometimes called

"rvalue" is in this document described as the "value of an expression".

An obvious example of an lvalue is an identifier of an object. As a further example, if E is a unary expression that is a

pointer to an object, *E is an lvalue that designates the object to which E points.
