The command line is represented in C or C++ as a call to main with two arguments...
int main (int argc, char* argv[]);
The argc variable is the number of arguments, and is always at least 1, because the first argument, argv[0], is the program name itself.
Each word in the command line is then presented in successive argv[n] variables. For instance, if you type thiscommand one two three, argc will be 4, and argv[n], n being 0 through 3, will be "thiscommand", "one", "two", and "three", without the quotation marks, of course.
Some implementations provide other functionality, such as an additional char *envp[] argument which contains the environment, but that is not ANSI. In the MS Windows environment, the entry point is to winmain for windows programs, and to main for console programs.
int WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPTSTR lpCmdLine, int nCmdShow);
In this case, the full command line is in lpCmdLine.
Other operating systems may have alternate entry points, but I do not know them as well as MS Windows. Other contributors - please refine this answer if appropriate.

There is no such thing as a null printer in C++. You are perhaps thinking of the null device to which output can be redirected from the command line (effectively hiding the output of a program). However this has nothing whatsoever to do with C++, it is entirely dependant upon the operating system.

What is argument in c plus plus?
If this is a homework assignment, please consider trying to answer it yourself first, otherwise the value of the reinforcement of the lesson offered by the assignment will be lost on you.An argument (or parameter) in C or C++ is a special variable that is passed to a function when it is called.

How does xcode 3.2 work with c plus plus?
XCode is really nothing more than a GUI front-end for a wide-variety of coding tools. Both C and C++ are built-in to the Mac operating system so you can use the cc command line tool to compile both C and C++, however most users prefer a GUI to the command line, thus gaining the advantage of a more integrated development environment (IDE). XCode integrates with gcc, which is better suited to cross-platform development than the built-in cc compiler.
