need C# advice

[Deathnote]

guyz d activity is to let the user input a number and the program should output a string version of it...
i already got it but wondering if this can be shorter...cause its a very long code...tnx for those who would reply

string[] ones = new string[]{"one","two","three","four","five","six","seven"," eight","nine"};
string[] tens = new string[]{"ten","twenty","thirty","fourty","fifty","sixty", "seventy","eighty","ninety"};

string h,o,t;
Console.Write("Enter Number: ");
string num = Console.ReadLine;
if (num.length==3)
{

for(y=0;y<=9;y++)
{
if(num[0]==y)
{
h= ones[y] + " " + "hundred";
}

if(num[1]==y)
{
t = tens [y] + " ";
}
else
{
t= "";
}
if(num[2]==y)
{
o= ones[y];
}

}

}
if (num.length==2)
{

for(y=0;y<=9;y++)
{


if(num[0]==y)
{
t = tens [y] + " ";
}
else
{
t= "";
}
if(num[1] == y)
{
o= ones[y];
}

}

}
else
{

for(y=0;y<=9;y++)
{



if(num[0] == y)
{
o= ones[y];
}

}

}
Console.Write(h + " " + t + " " + o);
Console.ReadLine();

P.S. Before receiving all the flames i would just like to say i did my best..its the shortest way i can think of...but just incase there is a better way it would be nice to know so ill learn more

kalas kaau ka ug loop brad.. usba na na one loop ra ug switch lng gamita para dali masabtan imong code.
use prepend pud para dili na ka 3 variables anang h o t nimo

[bluedes]

string numstring = "";
int tempnum;

if (num.length == 3)
{
tempnum = (int) num[0];
if (tempnum != 0)
{
numstring = ones[tempnum - 1] + " " + "hundred ";
}
tempnum = (int) num[1];
if (tempnum != 0)
{
numstring += tens[tempnum - 1] + " ";
}
tempnum = (int) num[2];
if (tempnum != 0)
{
numstring = ones[tempnum - 1];
}
}
else if (num.length == 2)
{
tempnum = (int) num[0];
if (tempnum != 0)
{
numstring += tens[tempnum - 1] + " ";
}
tempnum = (int) num[1];
if (tempnum != 0)
{
numstring = ones[tempnum - 1];
}
}
else if (num.length == 1)
{
tempnum = (int) num[0];
if (tempnum != 0)
{
numstring = ones[tempnum - 1];
}
}

double check lng kung naa sayop..

bosing pang 3 digit number ra ni xa??

Got this one from google a while back ... much longer but much more complete in providing english translation of a number:

Able to give sample run like:

Enter a number:
1234
You entered: [one thousand two hundred thirty four]

Enter a number:
602
You entered: [six hundred two]

Enter a number:
-12678902
You entered: [negative twelve million six hundred seventy eight thousand nine hundred two]

yup 3 digits ra bai...nindota ana imo sir kolz oi...libog pa lang for me kay dont know what indexof() method is and some of the other codes...but studyuan nako na unya

sir bluedes sakto bitaw na imo..damn nag lisod lisod man ko for loop...reallly need to learn alot pa

question lang sir...is "(int)num[0]" similar to "int.parse(num[0])"?

[moz_k2]

string[] ones = new string[]{"one","two","three","four","five","six","seven "," eight","nine"};
string[] tens = new string[]{"ten","twenty","thirty","fourty","fifty","sixt y", "seventy","eighty","ninety"};

imo nalimtan ang eleven to nineteen

[eax]

Try kuno gamit ug hashtable.

[Deathnote]

imo nalimtan ang eleven to nineteen

ahh bitaw noh...damn ni samot ug libog...hehehe

unsa nang has table bai? search sa nako kay bestfriend google

[bishop__]

para ma shorten ang program bai, then dynamic ang number of digits ma support, maayo gyud mag gamit ug % bai.
