A simple program with a tough logic!!!

[akshayakrsh]

hi everyone



this question came to my mind and has troubling me now for almost a month....
so guys plz help me on this!!!

the program is very simple. in it a user has to enter a no. and what he gets the output is the same no. but in words instead of figures i.e. the output is somewhat like as follows:


Enter a no.:1121
The no. is:One thousand one hundred and twenty one



now that's what i want!!! and if anybody does this for me i'll be highly obliged!!!!

so guys i m waiting for ur answers!!!

Take this as a start:

Number to Text Demo [VB5]
This demonstration program shows how to convert numbers to English as you might see in a check writing program. For example, 12345.67 is converted to "Twelve thousand, three hundred forty-five and 67/100".[1]

i just forgot to mention the main point!
i m sorry about that!
the point is i wanna do this using C/C++
i m sorry again!
plz send me the answers!

A simple solution whould be to break down your original number in digits, and parse those digits one by one, using a switch/case-statement. In psuedo, you'd get something like this:

var $number = 1234
var $thousands = 1
var $hundreds = 2
var $tens = 3
var $ones = 4

switch ($thousands)
{
case: 1:  $thousandstring = "One thousand "; break;
case: 2:  $thousandstring = "Two thousand "; break;
case: 3:  $thousandstring = "Three thousand "; break;
// etc
}

switch ($hundreds)
{
case: 1:  $hundredsstring = "One hundred "; break;
case: 2:  $hundredsstring = "Two hundred "; break;
// etc
}

// do the same for the tens and ones

// finally, concat the four strings you got:
$result = $thousandstring + $hundredsstring + $tensstring + $onesstring;

var $number = 1234
var $thousands = 1
var $hundreds = 2
var $tens = 3
var $ones = 4

switch ($thousands)
{
case: 1: $thousandstring = "One thousand "; break;
case: 2: $thousandstring = "Two thousand "; break;
case: 3: $thousandstring = "Three thousand "; break;
// etc
}

switch ($hundreds)
{
case: 1: $hundredsstring = "One hundred "; break;
case: 2: $hundredsstring = "Two hundred "; break;
// etc
}

// do the same for the tens and ones

// finally, concat the four strings you got:
$result = $thousandstring + $hundredsstring + $tensstring + $onesstring;

hey i know this will work in C/C++ but plz tell me what header files i'll require to run this program especially "var"!!!!!

do tell me
thnx anyway!

remark 1: take care of exceptions. all you need is given in the vb I attached:

        Ones(0) = "zero"
        Ones(1) = "one"
        Ones(2) = "two"
        Ones(3) = "three"
        Ones(4) = "four"
        Ones(5) = "five"
        Ones(6) = "six"
        Ones(7) = "seven"
        Ones(8) = "eight"
        Ones(9) = "nine"
        Teens(0) = "ten"
        Teens(1) = "eleven"
        Teens(2) = "twelve"
        Teens(3) = "thirteen"
        Teens(4) = "fourteen"
        Teens(5) = "fifteen"
        Teens(6) = "sixteen"
        Teens(7) = "seventeen"
        Teens(8) = "eighteen"
        Teens(9) = "nineteen"
        Tens(0) = ""
        Tens(1) = "ten"
        Tens(2) = "twenty"
        Tens(3) = "thirty"
        Tens(4) = "forty"
        Tens(5) = "fifty"
        Tens(6) = "sixty"
        Tens(7) = "seventy"
        Tens(8) = "eighty"
        Tens(9) = "ninety"
        Thousands(0) = ""
        Thousands(1) = "thousand"   'US numbering
        Thousands(2) = "million"
        Thousands(3) = "billion"
        Thousands(4) = "trillion"

remark 2: how to get the digits:

...
thousands=int(your_number)/1000;
your_number-=1000*thousands;
...
hundreds=int(your_number)/100 ;
your_number-=100*hundreds;
...

Can you do the rest?

Cheers


/edit: some output example

...
if (thousands!=0)
   printf("... %s thosand\t",ones[thousands]);
if (hundredss!=0)
   printf("... %s hundred\t",ones[hundreds]);
...

one more thing above in the code we are making cases but what in case of 99000, will i hav to 99 cases each time? is there a more simpler way?

[SirDice]

Have a look at the Lingua::Num2Word perl module.

Edit: Ah. You need something in C/C++

[akshayakrsh]

hey sec_ware
this may sound stupid
but what u have given is VB, right?
but i want it in C/C++
thnx anyway

[akshayakrsh]

thank u SirDice that really worked
