Declare m" means say int m if you say m = (int)f; // it means the int value of f is assigned to m The casting is actually not even necessary here: m=f; //works just as well now you can print m cout.

This truncates (aka, rounds down). Round(f) from #include is better, but your solution does provide an insight into how one might go about implementing a rounding function. – Niki Yoshiuchi Apr 8 '10 at 22:25.
You need to Declare m. A declaration looks like this: double a, be , c , d , e, f; Call a rounding function or change the default rounding that occurs when you use =. Assigning a double value to an int variable rounds down by default.
You can change the default with fesetround( FE_TONEAREST ); from #include . Alternately you can call the function round from #include . Neither of these functions are currently strictly standard C++; they are standard C and are scheduled to become standard C++.
Add a statement to print m, using cout and.
You should refer to class notes instead of Stack Overflow if you have them. – Potatoswatter Apr 8 '10 at 21:55 doing myself... – SkyBoxer Apr 8 '10 at 22:08 1 Do you have a book? – GMan Apr 8 '10 at 22:19.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
