hey anji,
jagged array is actually array of array in which number of column for each row is different

so here from
for (int j = 0; j < intJaggedArray[i].Length; j++)
{
System.Console.Write("{0}{1}", intJaggedArray[i][j], j == (intJaggedArray[i].Length - 1) ? "" : "");
}

intJaggedArray[i].Length we can know the column/length of i th row
and it is iteration through column of i th row so from "j == (intJaggedArray[i].Length - 1) ? "" : "")" we can come to know that is j at the last position/column of the i th row or not
