According to C++ Standard 2003: An lvalue (3.10) of a non-function, non-array type T can be converted to an rvalue.
Why don\'t rvalues have a memor开发者_开发百科y address? Are they not loaded into the RAM when the program executes or does it refer to the values stored in processor registers?Your question (\"Why do
string foo() { return \"hello\"; } int main() { //below should be illegal for bindin开发者_StackOverflow中文版g a non-const (lvalue) reference to a rvalue
I am trying to understand why someone would write a function that takes a const rvalue reference. In the code example below what purpose is the const rvalue reference function (returning \"3\").
#include &开发者_如何学运维lt;stdio.h> int main() { int i = 10; printf(\"%d\\n\", ++(-i)); // <-- Error Here
(Prompted by an answer.) Given N3290, §7.1.6.2p4, where the list items are unnumbered, but numbered here for our convenience:
The following code #include <vector> #include <string> #include <iostream> std::string const& at(std::vector<std::string> const& n, int i)
This question already has answers here: Closed 11 years ago. Possible Duplicate: What are rvalues, lvalues, xvalues, glvalues, and prvalues?
I\'ve been reading quite many on the Internet and it seems that many people mentioned the following rules (but i couldn\'t find it in the standard),
I wa开发者_JAVA技巧nt to pass an rvalue through std::bind to a function that takes an rvalue reference in C++0x.I can\'t figure out how to do it.For example:
