There are five or six sub-problems there. I think you
should post some code to show that you are at least trying
and also to show where your problems are. Unless you do
post some code, I predict you will get no further help.
The following i have tried
Ok, that doesn't compile on my system.
iostream.h possibly doesn't (and probably shouldn't) exist.
It definitely should exist, for reasons of backward
compatibility. Many implementations, however, provide a
version of it which isn't backward compatible. And you may need
special compiler flags to get at it.
What is certain is that someone learning C++ today shouldn't be
The iostream stuff is all in "namespace std" (read up about
namespaces if you're not familiar with them). Same for cin.
If he's using <iostream.h>, it shouldn't be in std::.
Hmmm... think of a simple test for oddness (or for evenness).
Hint: what do you get when you divide an odd "int" value by 2
Better yet, what is the definition of an odd number? And is
there an operator which could give the required information. (I
wouldn't use division.)
However you do it, "odd" is surely not the right name for what
you want to print out.
Yes and no. His output looks pretty odd to me.
Not sure why you want this... but if you do you probably have
to "#include <cstdlib>" or "#include stdlib.h" before main()
I've never used it either, but it would seem that some IDE's
don't know how to handle command line programs correctly. (At
least if they're not configured correctly. I've heard that you
can configure them so the behave correctly, but I've never
followed up on it.)
