This program is returning output as string, lets go to an example. Such as, if you enter a number 19, then this program will return “Nineteen”. So shall we do it????
[csharp]
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConvertNumericToString
{
class Program
{
static void Main(string[] args)
{
do
{
Console.WriteLine("Please enter the number..");
int intNum = Convert.ToInt32(Console.ReadLine());
Console.WriteLine(CheckAndDisplayString(intNum));
Console.WriteLine("Do you want to continue ..Y/N?");

} while (Console.ReadLine().ToLower() == "y");
Console.ReadLine();
}

private static string CheckAndDisplayString(int intNum)
{
try
{
var str1To19 = new string[] { "zero", "one", "two",
"three", "four", "five", "six",
"seven", "eight", "nine", "ten",
"eleven", "twelve", "thirteen",
"fourteen", "fifteen", "sixteen", "seventeen",
"eighteen", "nineteen"};
var strMultipleOfTen = new string[] { "twenty", "thirty",
"forty", "fifty", "sixty", "seventy",
"eighty", "ninety" };
//If the Number is zero return null
if (intNum == 0)
return "zero";
//check the 100 digit
string strResult = "";
int intDigit;
if (intNum > 100)
{
intDigit = intNum / 100;
intNum = intNum % 100;
strResult = str1To19[intDigit] + "hundred";
}
if (intNum == 0)
return strResult.Trim();
if (intNum < 20)
strResult += " " + str1To19[intNum];
else
{
//handles 10 digit
intDigit = intNum / 10;
intNum = intNum % 10;
strResult += " " + strMultipleOfTen[intDigit – 2];
if (intNum > 0)
strResult += " " + str1To19[intNum];

}
return strResult;
}
catch
{
return "The value you entered is not applicable..";
}
}
}
}
[/csharp]

Thank you 🙂
