#include <iostream>
例：void ProcessValue(int& i) 
{ 
	std::cout << "LValue processed: " << i << std::endl; 
} 
void ProcessValue(int&& i)
{ 
	std::cout << "RValue processed: " << i << std::endl; 
} 


int main() 
{ 
	int a = 0; 
	ProcessValue(a); 
	ProcessValue(std::move(a)); 
	return 0;
}

运行结果 :
LValue processed: 0 
RValue processed: 0
