看下编译器用的是C++的哪个标准。

C++17开始，lvalue有进一步区别

The C++17 standard defines expression value categories as follows:

A glvalue is an expression whose evaluation determines the identity of an object, bit-field, or function.

A prvalue is an expression whose evaluation initializes an object or a bit-field, or computes the value of the operand of an operator, as specified by the context in which it appears.

An xvalue is a glvalue that denotes an object or bit-field whose resources can be reused (usually because it is near the end of its lifetime). Example: Certain kinds of expressions involving rvalue references (8.3.2) yield xvalues, such as a call to a function whose return type is an rvalue reference or a cast to an rvalue reference type.

An lvalue is a glvalue that is not an xvalue.

An rvalue is a prvalue or an xvalue.
