WEBAug 30, 2010 · An rvalue (so-called, historically, because rvalues could appear on the right-hand side of an assignment expression) is an xvalue, a temporary object or subobject thereof, or a value that is not associated with an object. A prvalue (“pure” rvalue) is an rvalue that is not an xvalue.

WEBFeb 26, 2024 · Each C++ expression (an operator with its operands, a literal, a variable name, etc.) is characterized by two independent properties: a type and a value category. Each expression has some non-reference type, and each expression belongs to exactly one of the three primary value categories: prvalue, xvalue, and lvalue .

Some examples: std::string s; std::string foo(){ return "foo";} struct X { std::string s; }; std::string& bar() {return s;} void baz(std::string const& x){} s=std::string("hello"); // 1 s=foo(); // 2 std::string s2=bar(); // 3 baz("hello"); // 4 s=X ...

The following diagram illustrates the relationships between the categories: The diagram begins with a box labeled expression, which has two children: glvalue and rvalue. glvalue has two children: lvalue and xvalue. rvalue has two children: prvalue and xvalue; xvalue is also a child of glvalue.

WEBDec 23, 2023 · An rvalue (pronounced “arr-value”, short for “right value”, and sometimes written as r-value) is an expression that is not an lvalue. Rvalue expressions evaluate to a value. Commonly seen rvalues include literals (except C-style string literals, which are lvalues) and the return value of functions and operators that return by value.

WEBNov 16, 2020 · Every C++ expression is either an lvalue or rvalue. Roughly, it’s an lvalue if you can “take its address”, and an rvalue otherwise. For example, if you’ve declared a variable int x;, then x is an lvalue, but 253 and x + 6 are rvalues. If you can assign to it, it’s definitely an lvalue.

While an l-value reference is created using a single ampersand, an r-value reference is created using a double ampersand:

WEBa = b; // ok. b = a; // ok. a = a * b; // ok. // a * b is an rvalue: int c = a * b; // ok, rvalue on right hand side of assignment. a * b = 42; // error, rvalue on left hand side of assignment. In C++, this is still useful as a first, intuitive approach to lvalues and rvalues.
