         else if(arr[arr_i]<0) negative--; 
        else zero++;
         }
      P=positive/n;   N=negative/n;   Z=zero/n;

      Hello,

      Your code is running on some logical error. Here is why:

      1. line 18: it must not be decremented but incremented
      negative++;
      1. Line 21: for the formula of finding the decimal, you must explicitly convert or typecast the n to float since at start, it is of type int.

      Try it out.
