Chapter 11.8, Problem 11.31CP

Explanation of Solution

“rvalue” reference:

• An “rvalue” reference represents a temporary object that has no name.
• This temporary object cannot be accessed from other chunks of the code.

Example:

// Example program

// Include the needed header files

#include <iostream>

#include <string>

using namespace std;

// Function definition to cube value of a number

int cube(int x)

{

    // Return the cube value

    return x*x*x;

}

// Main method

int main()

{

    // Declare and initialize a variable

    int y = 0;

    // Assign a new value

    y = 6;

    // Display the value...
