what are the defferent between c++ and g++? anybody can xplaine it to me? thanx

c++ is a language. g++ is one of many compilers for the c++ language

Google can explain..

I don't have a Linux development environment on me right now, but I vaguely recall that c++ is also the name of one of the symlinks to gcc in some Linux distributions. 'cpp' and (less likely) 'cxx' might be others.

So as far as "c++" and "g++" are names of commands, there is no difference.

However, I sense this was not your question. Kudos to selket for his answer.

It's as selket said: c++(cpp) is a language and g++(gcc) is a kompiler for c++.

Actually on UNIX boxes it is a little more than all of that.

The command c++ is usually the native C++ language compiler from the vendor. This could be a proprietary version of the tool (Sun used to license their compilers and development tools).

Now g++ is the GNU C++ compiler, usually known as g++. This is just one component of the GCC project (GNU Compiler Collection)
