Setw undeclared?

Setw undeclared?
I think you need to include iomanip.h first... like this...





#include %26lt;iomanip.h%26gt;





These kinds of errors just mean that you lack the required headers to include... (^^,)

Reply:Have you included these files? If not this can cause that error.





#include %26lt;iostream%26gt;


#include %26lt;iomanip%26gt;





Also, omitting declarations like:


   using namespace std;


can cause errors too, although if you use the std:: format you can leave using declarations out sometimes.
