    Compiling syntax

    Sorry, this may be a newbie question..

    When compiling, for example g++ -c filename.cc....or
    g++ -o filename.o filename2.o

    what does the "-o" and "-c" do exactly?

    is there a help command where i can see all the available options for compiling and get more information?

    maybe like "help g++" (I've tried that, didn't work ....)

    (gcc) invokes a compiler which turns your source code into an object (o) file...

    (gxx) invokes a linker which in turn transforms your object files (o) into an executeable file (exe)

    hope that helps...

    The defualt executable filename after you compile is a.out, the -o flag lets you choose the executable filename.
    To find out about all of the options for gcc try:
    man gcc
    or
    gcc --h
