Okay, but considering the following 7 is not exactly the same as a
instance of a class:
class A
{
public:
A(){}
A(A const &){}
A& ref()
{ return *this; }
};
void f(A&){};
int main()
{
int *i = &3; // error: non-lvalue in unary `&'
A *p = &A(); // warning: taking address of temporary
f(A().ref()); // works fine, even though ref is a non-const
memberfunction
f(A()); // error: could not convert `A()' to `A&'
}
Btw p is a pointer to a non-const A, so is a temporary object const or not?
so why do the 2nd and 3rd line work and the 4th does not?
