@Tanish
Could you please specify which of these two questions are you trying ?
Both of these are for Pascal Triangle pattern and the only difference is in spacing.

Also your code is not giving an error but rather wrong outputs. Your code shows negative values on the right and is missing the first column of ones on the left.
Pascal triangle isn’t just a pattern with counting. You have to add the terms above the current term to get the current term. Your output seems entirely wrong. I suggest you to make some modifications in your current approach regarding these problems or try an alternate approach.
Here are some suggestions :

  1. Use an array to store the values and you can simply add the above terms from the previous row to compute the next element.
  2. Alternatively you can use this formula to compute the next value without array.
    value = value * (i - j) / j;
    where value is initialised as 1 in the beginning before the loops start . i represents row number and j represents column number
