Hi,
As a general rule we don't do your homework for you. If you have made a fair attempt at the question, show us how far you got and we'll nudge you in the right direction. For example, for your question, what have you tried or what do you think will be a good solution? Show us you've made some effort and we'll be more likely to help.

i have only this, but the main part (finding the third digit i don't have an idea,thinking about 2 hours) is difficult to find the solution.

``````Console.WriteLine("enter a number");
int number;
string c;
bool check = int.TryParse(c, out number);
while (check == false)
{
Console.WriteLine("please enter a valid number");
check = int.TryParse(c, out number);
}
``````
