If you have appropriate privileges on web server, you can upload to it C/C++ source code, compile it and execute. To do that you need shell access to server. If you don't have access to shell at web server — you can use Web Console.

Below you can find simple instructions to compile and execute C/C++ programs on web server:

• First of all you should make sure that you have access to GCC, G++ or CC compiler. For that just execute following shell command:
  

  For GCC:
  shell> gcc --help
  For G++:
  shell> g++ --help
  For CC:
  shell> cc --help

• If you see output like that:
  

  For GCC:
  Usage: gcc [options] file...
  For G++:
  Usage: g++ [options] file...
  For CC:
  Usage: cc [options] file...

  It means, that you can use compiler.
• In case of error, may be full path command can helps:
  

  shell> /usr/bin/[gcc, g++ or cc] --help
  shell> /usr/sbin/[gcc, g++ or cc] --help
  shell> /usr/local/bin/[gcc, g++ or cc] --help
  shell> /usr/local/sbin/[gcc, g++ or cc] --help
  shell> /bin/[gcc, g++ or cc] --help
  shell> /sbin/[gcc, g++ or cc] --help

• The next step is preparing source code for compilation. You can upload some C/C++ source code file to web server. Also you can write simple "Hello word" example program, to do that just execute following shell command:

  shell> echo 'main () { printf("Hello World\n"); }' > test-bin.c

  That comand will put at file "test-bin.c" source code of simple "Hello word" program, that will print at screen string "Hello word".
  Example you can see at following screenshot:

• To compile source code, just execute following shell command:
  

  For GCC:
  shell> gcc test-bin.c -o test-bin
  For G++:
  shell> g++ test-bin.c -o test-bin
  For CC:
  shell> cc test-bin.c -o test-bin

  That comand will compile file "test-bin.c" and will write binary executable at file "test-bin".
• Finally — execute binary:

  shell> ./test-bin

  For our simple "Hello word" example program you should see following output:

  Hello World

  Example you can see at following screenshot:

To find more information about GCC, G++ and CC command-line parameters just execute following shell commands:

shell> gcc --help
shell> g++ --help
shell> cc --help

Or if you want to read manuals — execute following shell commands:

shell> man gcc
shell> man g++
shell> man cc
