ahh thank you so much I was copying it right out of the book and the author didn't have that so i thought i wouldn't need it either but i guess i was wrong thanks

Yep, when you get stuff like (this standard function) undeclared, you're either missing the include or missing the namespace.

`cout' undeclared (first use this function)
