C# Question

i want all the numbers with 3 digits that have the sum of 9 to be write in the console.

This is what i came up so far and it doesnt work:

`class Program`

{

static void Main(string[] args)

{

int sum = 0;

for (int n = 100; n < 1000; n++)

{

while (n <1000)

{

sum += n % 10;

n /= 10;

if (sum == 9)

Console.WriteLine(sum);

}

}

}

}

I'd use three loops, one for every digit:

```
for (int i1 = 1; i1 < 10; i1++)
for (int i2 = 0; i2 < 10; i2++)
for (int i3 = 0; i3 < 10; i3++)
{
if (i1 + i2 + i3 == 9)
Console.WriteLine("{0}{1}{2}", i1, i2, i3);
}
```
