Create octal constant by starting with 0, followed by a sequence of digits in the range 0 through 7 in CSharp

using System;//ww w  .  j  a  v  a  2  s .c o m

public class MainClass{
    public static void Main() {
        //The digits 8 and 9 are errors in specifying an octal constant.
        int i = 0377;   // Octal constant
        int j = 0397;   // Error: 9 is not an octal digit
        Console.WriteLine(i);
        Console.WriteLine(j);
