Hi Michael. The c++ compiler would be called g++, which is also the command to invoke it.
One correction though. If you do > gcc csimple.c -o csimple.o (or what you will probably do with c++) > g++ cppsimple.cpp -o cppsimple it actually compiles directly into executable code, bypassing generation of an object file. That is this command actually does two things - it compiles your source code into object code and then generates an executable out of the object file. The first part is called "compilation" and the second is called "linking". If you do (note the "-c" flag) > gcc -c csimple.c -o csimple.o it will only generate an object file, which you can not execute. You can perform linking with it by doing the following: > gcc csimple.o -o csimple Usually, when your program is short then you put all code in one file and compile it the way you did with your c program. Except without giving the output file ".o" extension, because even though in Linux (unix) file extensions don't mean as much as they do in, say, Windows, it's a convention that ".o" files are object files generated by a compiler. Compiling your source files into object code will come in handy when your programs grow in size and you will want to split your programs in multiple source files and compile them separately. But that's going to be a little later :-) Cheers, Victor Prosolin.
