Given the class hierarchy in the box on page 810 and assuming we add a function named foo to MI as follows:

int ival;double dval;void MI::foo(double cval){    int dval;   // exercise questions occur here}

(a) List all the names visible from within MI::foo.

---

(b) Are any names visible from more than one base class?

---

(c) Assign to the local instance of dval the sum of the dval member of Base1 and the dval member of Derived.

---

(d) Assign the value of the last element in MI::dvec to Base2::fval.

---

(e) Assign cval from Base1 to the first character in sval from Derived.
