    1. You can change your for loop as under to print negative integers:

      for(i=0; i>=-5; i--)
      {
      printf("%d ", i);
      }

    1. Dear MJ,
      Thank you for referring this blog.
      When no value of N is taken from user, in that case program becomes static. For example, to print 1 2 3 4 5 one can write a for loop as shown below:
      for(i=1; i<=5; i++)
      { printf("%d ", i); }
