ios::flags
Hi, I am brand new to C++, and my teacher has given an assignment which he wants us to display values in scientific 'e' notation, but with an uppercase 'E'. He mentioned an ios::uppercase flag, which I can't get to work. Can anyone help me?
Here is what I've got so far.
#include <ios>
cout.setf(ios::uppercase) << my_value << endl;
I followed an example I found almost exactly, but the setf statement causes about 20 errors. I'm writing a Win32 console application using the visual studio.net 2003 compiler.
thanks in advance,

Try using manipulators, like this: cout << uppercase << scientific << my_value << endl; This is equivalent to cout.setf(ios::uppercase); cout.setf(ios::scientific, ios::floatfield); // or both flags can be set in one operation // cout.setf(ios::uppercase | ios::scientific, // ios::uppercase | ios::floatfield); cout << my_value << end; -- With best wishes, Igor Tandetnik
