Create a program that prompts the user to enter a number (0-900only) then output the number in words.

Enter a number: 12
it outputs " twelve"
can you please tell me what are my errors ?

im also having a problem with the 11-19 when i inut 11 it becomes "tenone" instead of eleven

heres my code

Please re-post this with the code tags -- you will find them under Format.

Also, I don't see where you handle the case of eleven.
Bdanielz (506)
Good call @koothkeeper I think he needs to handle 11-19 (Teens) separately. It is weird those 11-19 seem to be the the weird deviations in how we speak numbers.

koothkeeper (429)
I agree @Bdanielz: That number range is weird in other languages too.

but we are not aplicable to use if/else statement i really dont know what to do
dhayden (5798)
Use arrays to store the words. For example:
1
2
3
4
5
6
7
 
    static string ones[] =
	{"one ", "two ", "three ", "four ", "five ", "six ", "seven ", "eight ", "nine "};
    static string teens[] =
	{"ten ", "eleven ", "twelve ", "thirteen ", "fourteen ", "fifteen ", "sixteen ", "seventeen ", "eighteen ", "nineteen "};

    static string tens[] =
	{"twenty ", "thirty ", "forty ", "fifty ", "sixty ", "seventy ", "eighty ", "ninety "};


Then just accumulate the words for large values and reduce the number. This fragment will do up to 99. Note that I made zero a special case:
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
20
21
 
    string result;

    if (n == 0) {
	result = "zero ";
    }

    if (n >= 20) {
	result += tens[(n / 10) - 2];
	n %= 10;
    }
    if (n >= 10) {
	result += teens[n-10];
	n = 0;
    }
    if (n > 0) {
	result += ones[n-1];
    }

    // The value ends with a space, trim it off.
    result.resize(result.size()-1);
    return result;


This should give you an idea of how to add code to deal with hundreds. This is part of a funciton I have that converts 64 bit numbers to words.
