Hi,
I don't remember what the original Warning was, but what about a cast like 0.5F or 0.5D. I can't remember but I think thats how youcast a constant. I never did it, but it might fix the warning. ----- Original Message ----- From: "James Panes" <jimpanes@xxxxxxxxx>

Hi guys,

I'm just making an educated guess here.

I think that "0.5" is being considered to be a float type. this does not
make any sense because it is in fact a literal constant.

Try declaring the variables as type double.
Or is that bad programming?

Martin is rught.
Again, do not assume that the compiler is aware of what you want to
do. It is trying to concider it as a function call ... if you want to
multiply use the * symbol. And, again, please point the error and in
what line it is in your first message, which will make it easier for
us to help you.

Well, the what the program should do is there, but the line that is

> gross = wage * hours + 0.5 (hours - 40);

for some reason, the compiler doesn't like it.
error is
Error 1 error C2064: term does not evaluate to a function taking -22
arguments

I usually do walk away for a bit when I get frustrated but it's the
headaches I get after going back a few times that are really starting to
concern me. I know I'm close, if I do different, easier math in that line
like just adding 1 or something it will work changing it a bit, but
when I
do it this way, which looks right to me, it just doesn't like it. I'm
sure
I'm missing something simple again. I've been close right along I feel
like,
but lagging behind, I'm not sure if it's me, a Braille display would have
probably helped with the last one but I can't afford that and was pretty
much told "no" by the state when I wanted one for another class, it's too
late now anyway week 5 or 10 starts tomorrow.
