QUESTION: Convert numbers to words

[amplechin]

Create a program that prompts the user to enter a number (0-100000 only) then output the number in words.

Enter a number: 10012
it outputs " ten thousand two" instead of ten thousand twelve...
can you please tell me what are my errors ?

im also having a problem with the 11-19 ten thousandths case ...

here's my program...

#include <iostream>


using namespace std;


void main()
{


    int num,ones,tenths,hundredths,thousandths,tenthousandths,hundredthousandths;
 
    cout<<"Enter a Number: ";
    cin>>num;
 
    if (num==0)
        cout<<"zero";
    if (num>=0&&num<=100000)
    {
        hundredthousandths=num/100000;


        switch (hundredthousandths)
        {
        case 1:
            cout<<" one hundred thousand ";
            break;
        }


        tenthousandths=num/10000;


        switch (tenthousandths)
        {
        case 0:
            cout<<" ";

You need to do

place = num / x;
num = num % x;

at each step along the way.

I did this once for printing the words on a che(ck|que). what I did was to split the number up into 3-digit groupings. that way I only had to translate 3 digits into words, and then add a "thousand" or "million" or whatever to the end for each group.
