This group is really about the language, and not about using any
particular tools.

You could start by trying

gcc --help

and be welcome back when you have a program that does not compile or
work properly.

Use gcc for C and for C++ use g++.

g++ -Wall -ansi -pedantic -o <name> [file1, file2, ...]

But if you want to do it in correct way first of all you should build
Obj files.
g++ -Wall -ansi -pedantic -o <module_name> <module_file>
After you have all modules and main program compiled, link them.
g++ -o <program_name> [file1.o, file2.o, ...]

You do it exactly the same way you do with any compiler: you
read the documentation, very carefully, in order to choose the
options which are appropriate to what you're doing. I could
give you the options I use for compiling under Linux, but
there's absolutely no reason to suppose that they would be
appropriate for your circumstances.

If you use the correct filename extensions on your source files, then
the 'gcc' command will happily compile your C++ code. There is one
caveat -- if you make use of any StdLib functions, you will need to
tell 'gcc' to use the C++ library instead of defaulting to the C one.

From the 'man' page:

" Compiling C++ Programs

C++ source files conventionally use one of the suffixes .C,
..cc, .cpp,.CPP, .c++, .cp, or .cxx; C++ header files often use .hh
or .H; and preprocessed C++ files use the suffix .ii. GCC
recognizes files with these names and compiles them as C++ programs
even if you call the com$B!>(Bpiler the same way as for compiling C
programs (usually with the name gcc).

However, C++ programs often require class libraries as well as
a compiler that understands the C++ language---and under some
circumstances, you might want to compile programs or header files from
standard input, or otherwise without a suffix that flags them as C++
programs. You might also like to precompile a C header file with a .h
extension to be used in C++ compilations. g++ is a program that calls
GCC with the default language set to C++, and automatically specifies
linking against the C++ library. On many systems, g++ is also
installed with the name c++."
