Chapter 18, Problem 18.9E
(HugeInt 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 HugeInt of Figs. 18.17–18.19. Study the class carefully, then answer the following:
- Describe precisely how it operates.
- What restrictions does the class have?
- Overload the * multiplication operator.
- Overload the / division operator.
- 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.]

(Math: The Complex class)The description of this project is given in Programming Exercise 14.7 in the Chapter 14 Programming Exercise from the Book section. If you get a logical or runtime error, please refer https://liangcpp.pearsoncmg.com/faq.html.
Design a class named Complex for representing complex numbers and the functions add, subtract, multiply, divide, abs for performing complex-number operations, and the toString function for returning a string representation for a complex number. The toString function returns a+bi as a string. If b is 0, it simply returns a.
Provide three constructors Complex(a, b), Complex(a), and Complex(). Complex() creates a Complex object for number 0 and Complex(a) creates a Complex object with 0 for b. Also provide the getRealPart() and getImaginaryPart() functions for returning the real and imaginary part of the complex number, respectively.
Overload the operators +, -, *, /, +=, -=, *=, /=, [], unary + and -, prefix ++ and --,…

The data attribute of the LinkNode should be a reference/pointer of the Currency class of Lab 2. Do not make it an inner class or member structure to the SinglyLinkedList class of #2 below. A SinglyLinkedList class which will be composed of three attributes - a count attribute, a LinkNode pointer/reference attribute named as and pointing to the start of the list and a LinkNode pointer/reference attribute named as and pointing to the end of the list. Since this is a class, make sure all these attributes are private. The class and attribute names for the node and linked list are the words in bold in #1…

- Solve the problem in C++ (Geometry: find the bounding rectangle) A bounding rectangle is the minimum rectangle that encloses a set of points in a two-dimensional plane, as shown in Figure 11.9d. Write a function that returns a bounding rectangle for a set of points in a two-dimensional plane, as follows: const int SIZE = 2; Rectangle2D getRectangle(const double points[][SIZE]); Write another function that returns a pointer to the bounding rectangle as follows: Rectangle2D* getRectanglePointer(const double points[][SIZE]); The Rectangle2D class is defined in Programming Exercise 11.9.

(Numerical) a. Euclid’s method for finding the greatest common divisor (GCD) of two positive integers consists of the following steps:Step 1: Divide the larger number by the smaller and retain the remainder.Step 2: Divide the smaller number by the remainder, again retaining the remainder.Step 3: Continue dividing the previous remainder by the current remainder until the remainder is zero, at which point the last non-zero remainder is the GCD. For example, if the two positive integers are 84 and 49, you have the following: Step 1: 84/49 yields a remainder of 35.Step 2: 49/35 yields a remainder of 14.Step 3: 35/14 yields a remainder of 7.Step 3: 14/7 yields a remainder of 0. Therefore, the last non-zero remainder, which is 7, is the GCD of 84 and 49.Using Euclid’s algorithm, replace the stub function written for Exercise 14 with an actual function that determines and returns the GCD of its two integer arguments. thank you…arrow_forward
