    Ok, good. So the problem is likely with the dflag and/or dplace variable. When I look at that part of the code, I see that this:
    Code:
              if (dflag==1)
                {
                  dplace*=10;
                }
              pos++;
    is never actually called. It is not under a case statement. Where did you mean for that code to be run?

    any help would be great.
    Is this an academic exercise, or can you use standard functions that already do this (and much more thoroughly)?

    7. It is easier to write an incorrect program than understand a correct one.
    40. There are two ways to write error-free programs; only the third one works.*
