not really Qt related, but you can try to find something "here":https://www.google.com/search?q=Numbers+to+Words+Converter+c++ :)

Had to do this a while ago, here's my Qt based interpretation of what I found to be the an elegant solution.

static QString numberToText(uint number)
{
static QMap<uint, QString> numbers;//Only initialize once
if (numbers.isEmpty())
{
numbers[0] = "zero";
numbers[1] = "one";
numbers[2] = "two";
numbers[3] = "three";
numbers[4] = "four";
numbers[5] = "five";

Hi Everyone.
Is their any method which converts integer number to word, i.e.,
2 ---> Two,
23 ---> Twenty Three,
150 ---> One Hundred and Fifty etc.Thank you in advance.
