我想问一下有关将类型转换为T&&and 的问题const T&。

int&& ref = static_cast<int&&>(1); // will ref assign to free memory? or
const int& ref = static_cast<const int&>(1);

int&& func() {
    return 1;
}
// or
int&& func() { // call of this function always return free memory? 
    return static_cast<int&&>(1);
}

// does static_cast<> have some different forms from casting int() (int) ?
static_cast<int&&>(1),
static_cast<const int&>(1),
or func(); // do I understand right, reference destroys with object after ';' or it returns free …
