I have installed andLinux.
Then installed gcc and emacs using
apt-get install
command
they both installed ok.

And now the list of questions
1. Is there any configuration file that I can update with the gcc options so that any time I write in the terminal
gcc -c file.c
these options will be applied?

2. I don't see stdio.h and iostream files on my system. Have I to install some additional packages to get all c/c++ standard libraries and include files?

3. I'd like to intagrate the gcc and gdb into the emacs. What file should I edit to do it? currently choosing compile menu in emacs I got make -d prompt, I'd like to change it so the command automatically invoked by the emacs will be gcc with options I want

Thanks
