In this C# program, we will take the input number from the user and change it to Words. E.g. 1024 will be converted to One Thousand Twenty Four only.
C# Program to Convert Number into Words Code:
private static void Main(string[] args)
{
Console.Write("Enter a Number: ");
int number;
number = int.Parse(Console.ReadLine());
string word = ConvertNumberToWords(number);
Console.WriteLine("Number {0} in words is: {1} only.", number, word.Replace(" ", " "));
Console.ReadLine();
}
private static String[] ones = { "Zero", "One", "Two", "Three",
"Four", "Five", "Six", "Seven", "Eight", "Nine", "Ten", "Eleven",
"Twelve", "Thirteen", "Fourteen", "Fifteen", "Sixteen",
"Seventeen", "Eighteen", "Nineteen" };
private static String[] tens = { "", "", "Twenty", "Thirty", "Forty",
"Fifty", "Sixty", "Seventy", "Eighty", "Ninety" };
public static String ConvertNumberToWords(int i)
{
if (i < 20)
{
return ones[i];
}
if (i < 100)
{
return tens[i / 10] + ((i % 10 > 0) ? " " + ConvertNumberToWords(i % 10) : "");
}
if (i < 1000)
{
return ones[i / 100] + " Hundred"
+ ((i % 100 > 0) ? " And " + ConvertNumberToWords(i % 100) : "");
}
if (i < 100000)
{
return ConvertNumberToWords(i / 1000) + " Thousand "
+ ((i % 1000 > 0) ? " " + ConvertNumberToWords(i % 1000) : "");
}
if (i < 10000000)
{
return ConvertNumberToWords(i / 100000) + " Lakh "
+ ((i % 100000 > 0) ? " " + ConvertNumberToWords(i % 100000) : "");
}
if (i < 1000000000)
{
return ConvertNumberToWords(i / 10000000) + " Crore "
+ ((i % 10000000 > 0) ? " " + ConvertNumberToWords(i % 10000000) : "");
}
return ConvertNumberToWords(i / 1000000000) + " Arab "
+ ((i % 1000000000 > 0) ? " " + ConvertNumberToWords(i % 1000000000) : "");
