You can use cin which located in iostream.h You have to use certain data type to read string, for instance, array of char
The C++ compiler is invoked with g++, however on many systems it is installed as c++. Consult the documentation for information on the command line options.
C++ also supports C program's multiple command line /* your command */.
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.
The main function is the entry point of your application. Its primary purpose is to process command-line switches (if any) and to invoke the appropriate functions. For trivial applications the main function may be the only function, however separating blocks of code into re-usable functions make code much easier to read.
yes it can very much so read binary.
C++ is not a command oriented language, it is a multi-paradigm language because it employs functional and object-oriented approaches to programming.
Pipe the output to the MORE command.
In the Options menu the Arguments command.
Most, if not all, Linux distributions have the compiler you would need to compile c and c++ programs, gcc, or the gnu c compiler chain. If you type "gcc --help" into the terminal, it will give you a short list of command line arguments that are needed, as well as briefly explain the various command line arguments. Man (manual) pages can be read by typing "man gcc" at a terminal prompt. Man pages are very thorough (read: very long) explanations of every possible use for a program or command. If you do not have gcc installed (I don't know how you wouldn't), you should be able to use YAST to install it. Search for "gcc" and install the most recent package. You may need to install the header files, and possibly the kernel sources as well for some programming.
To skip to a new line when reading from a file, assuming you are using a sequentially organized file, the usual case, you need to read and discard characters until you encounter the end-of-line character.

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.
