int number = Convert.ToInt32(Console.ReadLine());

//your code goes here
string result = "";
int i = 1 ;

while ( i <= number )

if ( i % 3 == 0 )
{
result = result + '*';
}
else
{
result = result + i.ToString();

i++;

Console.WriteLine ( result );

}

Answer 1

This code will ask for a number (since you use Convert.ToInt32) and will write a string with ascending numbers (12345...) until the number given by the user, but it will skip the number and write a * on multiples of three.

Example:
Input:
10

Output:
12*45*78*10
