> Given the declarations in the previous exercise determine whether the following assignments are legal. Explain how the top-level or low-level `const` applies in each case.
>
> ```cpp
> r1 = v2; // legal, top-level const in v2 is ignored.
> r1 = v2; // illegal, we cannot bind reference of type "int &" to initializer of type "const int".
> p1 = p2; // illegal, p2 has a low-level const but p1 doesn't.
> p2 = p1; // legal, we can convert int* to const int*.
> p1 = p3; // illegal, p3 has a low-level const but p1 doesn't.
