You cannot have ! as a function name. It is the NOT operator.

Ah. still comes up with ...
"1>c:\users\katie\documents\visual studio 2010\projects\mathematic functions\mathematic functions\mathematic functions.cpp(43): warning C4715: 'factorial' : not all control paths return a value

long double factorial (long double m)
{
	long double a;
	if (a>1) 
long double (a* factorial (a-1));
else 
	return 1;
}
(also changed it in the other functions aswell)

Missing return on line 5?
Katieeee (11)
what you mean missing return...?
I've put return on line 6... isn't that the same (or do you mean on line 5 in my reply??)
Peter87 (11178)
Yes, I mean your reply.
Katieeee (11)
So i'm returning 'a' after or before long double (a*factorial (a-1))...?

its came up with 'illegal else without matching if' when i tried both of those...
Katieeee (11)
AH!! I got it... return instead of 'long double'. Thanks guys :)
