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.]

Working with pointers and dynamic memory. Indicators. Working with dynamic memory. Dynamic arrays and their use as function parameters.
Task :
Describe a void function named Swap(x,y) that swaps the values stored in the variables x and (x is a real type parameter and is both input and output). Using this function , for the given variables of real type a, b, c, d, one should sequentially replace the values of the pairs (a, b), (c, d) and (b, c) and let a, b, c, d be new values .
(c) Implement the function printer in C so that given the statements below, the printer
function would print:
Word 1 is one. The first letter of the word is o
Word 2 is two. The first letter of the word is t
Word 3 is three. The first letter of the word is t
Word 4 is four. The first letter of the word is f
Word 5 is five. The first letter of the word is f
The printer function should be capable of handling arrays of any size.
void printer(int sizeofNums, *char y[]); //prototype
char a[] = "one";
char b[]
char c[]
char d[]
char e[]
char *nums[]
%3D
"two";
= "three";
"four";
"five";
%3D
= { a,b,c,d,e };
printer (sizeof(nums), nums);
Please write a C++ coding with modularity using functions.
15. (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.

- ( In c++and oop ) without using vectors or data structure . Create a class IntegerSet for which each object can hold integers in the range 0 through 100. A set is represented internally as an array of ones and zeros. Array element a[ i ] is 1 if integer i is in the set. Array element a[ j ] is 0 if integer j is not in the set. • The default constructor initializes a set to the so-called “empty set,” i.e., a set whose array representation contains all zeros. • Provide member functions for the common set operations. For example, provide a unionOfSets member function that creates a third set that is the settheoretic union of two existing sets (i.e., an element of the third set’s array is set to 1 if that element is 1 in either or both of the existing sets, and an element of the third set’s array is set to 0 if that element is 0 in each of the existingsets). Provide an intersectionOfSets member function which creates a third set which is the set theoretic intersection of two existing sets…arrow_forward(Answers needs to be in pseudo-code, not in C++ ) Question Workspace a.
