a function call or an overloaded operator expression of rvalue reference to object return type, such as std::move(x); (注意:返回右值引用的表达式(方法和运算符重载),是消亡值,而不是纯右值) a[n], the built-in subscript expression, where one operand is an array rvalue ; ...

a = std::move(b);//std::move(b)为右值,这里会调用move assigment b = std::move(tmp);//std::move(tmp)为右值,这里会调用move assigment } 我们不禁要问:我们通过右值应用的绑定规则三和规则四,知道右值引用不能绑定到左值,可是std::move()函数是如何把上述的左值a、 b和tmp变成右值的呢?这就要...
