Thanks. Excellent article. Looking forward to lesson 2. I had been hesitant to download the developer tools until now. This article convinced me to give it a try.

  If you're anxious to get Mr. Roby's little sample to compile and run, let me give you a little nudge.
  
  Getting a C program to run involves three steps:
  1. Create your C source file. If you've never used vi or emacs then I would recommend pico. Save the source file as 'lesson1.c'.
  2. Compile it into machine code:
  gcc lesson1.c
  3. Run your program and see your happy result:
  ./a.out
  
  I'm not going to go into how or why any of this works; I will let the excellent tutorial run its course. I will, however, say that despite what you've read, the line that begins with '#' (it's not a comment) must remain as an independent line.
  
  
  Here is the entire program:
  
  #include <stdio.h>
  void main()
  {
  //Computes our favorite number
  int favoriteNumber = (3 * 4) / 2; /*is anyone's favorite number not an int? */
  favoriteNumber = favoriteNumber + 2;
  
  /* now let's tell the world
  what our favorite number is! */
  printf("My favorite number is %d!", favoriteNumber);
  }

  Presuming somebody interested in this tutorial is going to be working on a Mac, why would they bust out vi or emacs or pico?
  
  You can do all your typing in Project Builder. It's a perfectly servicable text editor. Or use BBEdit / BBEdit Lite. Much friendlier.

  Whoops! I should have tested the program before I hit 'Submit'. Here is the revised code:
  
  #include <stdio.h>
  int main()
  {
  //Computes our favorite number
  int favoriteNumber = (3 * 4) / 2; /*is anyone's favorite number not an int? */
  favoriteNumber = favoriteNumber + 2;
  
  /* now let's tell the world
  what our favorite number is! */
  printf("My favorite number is %d!\n", favoriteNumber);
  }

  Not really. return 0; is optional in standard, modern C++ - and by extension, I'd assume the most recent C spec.
  
  Though gcc accepts some C++ syntaxes in C-compiling mode.
