View the right value reference from four lines of code, and the right value reference from four lines of codeView overview of right value reference from four lines of code
The concept of right value reference may be unfamiliar to some readers. In
The Right value reference (and its supported move semantics and perfect forwarding) is one of the most significant language features that c++0x will join, which can be seen from the list of the features in the C + + state of the evolution. from a
1. Left value and right value:
C + + for the left and right values do not have a standard definition, but there is a widely accepted saying: You can take the address, the name, not temporary is the value of the left, can not take the address, there
Moving semantics of right-value reference and right-value reference Semantics
This article is translated from a classic article about the reference and interpretation of the right value. If you can still use English, go to the original English text.
A very important concept introduced in C ++ 11 is right value reference. Understanding the right value reference is the basis for learning "Move Semantics. To understand the right value reference, you must first distinguish the left value from the

1. Background introduced by right reference
The loss of efficiency caused by the generation and copying of temporary objects has always been a problem of C ++. However, the C ++ standard
Article 2: Transfer Using the right value reference
This is the second article in the series about efficient value types in C ++. In the previous article, we discussed how to eliminate the possibility of multiple replication operations. Replication

In C ++, the left value (lvalue) is the amount of addresses that can be obtained. Because it often appears on the left of the value assignment statement, it is called the left value. For example, a variable with a name. For example:
Int a = 10; // a
Right-value reference (and supported move semantics and perfect forwarding) is one of the most important language features C ++ 0x will add, this can be seen from the proposal of this feature ranking first in the C ++-state of the evolution list.

New features in C ++ 11: rvalue Reference (right value Reference)
The right value reference allows us to distinguish between the left and right values of an expression.
C ++ 11 introduces the concept of right value reference, so that we can bind the
