cc - Compile C source code, link-edit, and create an executable file

See c89/xlc or man xlc.
Note:
  1. The cc command is fully supported for compatibility with older UNIX systems. However, it is recommended that the c89 command be used instead because it may provide greater functionality and is considered the standard for portable UNIX applications as defined by POSIX.2 IEEE standard 1003.2-1992.
  2. When working in the shell, to view man page information about cc, type: man c89 or man xlc.
