(Huge Int Class) A machine with 32-bit integers can represent integers in the range of approximately -2 billion to +2 billion. This fixed-size restriction is rarely troublesome, but there are applications in which we would like to be able to use a much wider range of integers. This is what C++ was built to do, namely, create powerful new data types. Consider class Huge Int of Fig 1-3. Study the class carefully, then answer the following:

a) Describe precisely how it operates.

---

b) What restrictions does the class have?

---

c) Overload the * multiplication operator.

---

d) Overload the / division operator.

---

e) Overload all the relational and equality operators.

[Note: We do not show an assignment operator or copy constructor for class HugeInt, because the assignment operator and copy constructor provided by the compiler are capable of copying the entire array data member properly.]
