Problem: BigNumber
Integer numbers in programming limit how large numbers can be processed, so double types come to
the rescue. Sometimes we need to implement bigger values. Create a class BigNumber that uses a 40-
element array of digits to store integers as large as 40 digits each. Provide methods Input, ToString, Add
and Subtract. For comparing BigNumber objects, provide the following methods: IsEqualTo,
IsNotEqualTo, IsGreaterThan, IsLessThan, IsGreaterThanOrEqualTo and IsLessThanOrEqualTo. Each of
these is a method that returns true if the relationship holds between the two BigNumber objects and
returns false if the relationship does not hold. Provide method IsZero. In the Input method, use the
string method ToCharArray to convert the input string into an array of characters, then iterate through
these characters to create your BigNumber. (Add Multiply and Divide methods For extra five points in
next exam)
Hint: use char –‘0’ to convert character to integer
Assume the user enter only digits and – sing to the left such as -56894
// Driver Class
using System;
public class BigNumberTest
{
public static void Main(string[] args)
{
BigNumber integer1 = new BigNumber ();
HugeInteger integer2 = new BigNumber();
Console.Write("Enter first BigNumber: ");
integer1.Input(Console.ReadLine());
Console.Write("Enter second BigNumber: ");
integer2.Input(Console.ReadLine());
Console.WriteLine($"BigNumber 1: {integer1}");
Console.WriteLine($"BigNumber 2: {integer2}");
BigNumber result;
// add two BigNumbers
result = integer1.Add(integer2);
Console.WriteLine($"Add result: {result}");
// subtract two BigNumbers
result = integer1.Subtract(integer2);
Console.WriteLine($"Subtract result: {result}");
// compare two BigNumbers
Console.WriteLine(
$"BigNumber 1 is zero: {integer1.IsZero()}");
Console.WriteLine(
$"BigNumber 2 is zero: {integer2.IsZero()}");
Console.WriteLine(

$"BigNumber 1 is equal to BigNumber 2: {integer1.IsEqualTo(integer2)}");
Console.WriteLine(
$"BigNumber 1 is not equal to BigNumber 2:
{integer1.IsNotEqualTo(integer2)}");
Console.WriteLine(
$"BigNumber 1 is greater than BigNumber 2:
{integer1.IsGreaterThan(integer2)}");
Console.WriteLine(
$"BigNumber 1 is less than BigNumber 2:
{integer1.IsLessThan(integer2)}");
Console.WriteLine(
$"BigNumber 1 is greater than or equal to BigNumber 2:
{integer1.IsGreaterThanOrEqualTo(integer2)}");
Console.WriteLine(
$"BigNumber 1 is less than or equal to BigNumber 2:
{integer1.IsLessThanOrEqualTo(integer2)}");
}
