Help for C Programming Language Tools

C, the UNIX Programming Language:

• C Beginner Help:
  1. C in MathLab, 200SEO: Find a NeXT Terminal window by double clicking on the Terminal icon (looks like a display with the word "MACH" repeated on it) on the left hand side dock.
  2. If you need help, type
     man    cc
     for the UNIX manual help page for GNU C; press "SPACE" for one "more" page, type "q" to quit the "man" page. {Remark: do not forget to "RETURN" or "ENTER" for executing each command.}
  3. If you want to compile a C program, say "[pgm].c", (the GNU C compiler is located in "/bin/cc" in MathLab, so the "/bin" directory should be in your path; here "[name]" notation is used for something the user has to substitute a user actual name), type on the command line after the prompt:
     cc    -c    [pgm].c
  4. If you want to both compile and create a C executable named "[run]" (instead of the default name "a.out"), type
     cc    -o    [run]    [pgm].c
     or if you want to both compile and create a C executable named "[run]" and want the compile output to go to the file "[pgm.listing]", type
     cc    -o    [run]    [pgm].c<[pgm.listing]
  5. If you want to execute the executable file "[run]" with output and input at the terminal, type
     [run]
     or if you want to execute the executable file "[run]" with input file called "[pgm.input]" and with output going into the file "[pgm.output]", type
     [run]<[pgm.input]>[pgm.output]
     or if you want to run the executable in the background, so you can continue to use the NeXT Terminal window for checking the status with the UNIX "jobs" command, type
     [run]<[pgm.input]>[pgm.output]&
  6. If you want to read your output, use your favorite editor, like the UNIX "vi" visual editor with the command
     vi    [pgm.output]
     or the NeXT editor by finding the "[pgm.output]" in the NeXT file viewer Workspace.
