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:

    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);
