Using C++

Design a class called Numbers that can be used to translate integers in the range 0 to 9999 into an English description of the number.

The class should have a single integer member variable:

int number;

and a static array of string objects that specify how to translate the number into the desired format. For example, you might use static string arrays such as:

string lessThan20[20] = {"zero", "one", ..., "eighteen", "nineteen"};
string hundred = "hundred";
string thousand = "thousand";

The class should have a constructor that accepts a nonnegative integer and uses it to initialize the Numbers object. It should have a member function, print(), that prints the English description of the Numbers object.

Demonstrate the class in a main program that prompts the user to input a number and then prints out its English description.

Please find the code below:::

#include <iostream>
#include <vector>
#include <string>
#include <cmath>
using namespace std;
class Numbers
{
public:
   static int numbers;
   static void print();
};

void Numbers::print()
{
   int b;
   string lessThan20[] = { "zero","one", "two", "three", "four", "five", "six", "seven", "eight", "nine", "ten", "eleven",
           "twelve", "thirteen", "fourteen", "fifteen","sixteen", "seventeen", "eighteen", "nineteen" };
   string hundred = " hundred ";
   string thousand = " thousand ";
   string tens[] = { "zero", "ten", "twenty", "thirty", "forty", "fifty", "sixty", "seventy", "eighty", "ninety" };
   if (numbers < 0)
       cout << "it is a negative number";
   numbers = abs(numbers);
   b = numbers / 1000;
   if (b > 0)
       cout << " " << lessThan20[b] << thousand;
   numbers %= 1000;
   b = numbers / 100;
   if (b > 0)
       cout << lessThan20[b] << hundred;
   numbers %= 100;
   if (numbers>= 20)
   {
       b = numbers / 10;
       if (b > 0)
           cout << tens[b] << " ";
   }
   else if (numbers >= 10)
   {
       cout << lessThan20[numbers] << " ";
       return;
   }
   numbers %= 10;
   if (numbers > 0)
       cout << lessThan20[numbers];
   cout << " ";
}
int Numbers::numbers;
int main()
{
   int b;

   cout << "Please enter a number from 0-999 or enter 0 to Exit : "<<" ";
   cin >> b;
   while (b != 0)
   {
       cout << "The number " << b << " " << "would be translated into - "<<" ";
       Numbers::numbers = b;

       Numbers::print();
       cout << "\nPlease enter a number from 0-999 or enter 0 to Exit : "<<" ";

       cin >> b;
   }

   cin.ignore();
   cin.get();

   system("pause");
   return 0;
}

output:
