[Dev-C++] newbie trying to relate header files in books and documentation todev-c++

[John K. <jki...@po...>]

A program from a book for newbies (Accelerated C++) gave an example 
program using the header #include<ios>.

The gcc command-line compiler balked until I simply commented that 
line out. Reading the GNU documentation, it looks like <ios> is 
related to <iostream>, which *was* included in this program's header 
listings. Its inclusion is possibly why the program runs with the 
#includes<ios> line commented out.

Could someone explain the relatinship between those two header files? 
I don't find <ios> in my dev-c++ distro. Do I need it? Why would a 
program in a well-received book use a header declaration that can be 
commented out? Does the gcc version (2.952) I recently downloaded 
with dev-c++ need to be updated?

I don't like that I am having these problems with things like 
configurations and header files, but those are the issues I need to 
deal with since they are coming up at this early stage.
Thanks.
