Many of them are geology & psychology majors that got smart & decided to make some money. Not to mention Computer Learning Center.

Anytime anyone mentions anything about null pointers, casts, arrays vs pointers, portability, lint, etc. you feel compelled to enlighten them. I don't blame you for getting tired of it, but Guy Harris is not going to save the world. They'll learn. Besides, reading your treatises is almost as boring as reading dumb questions. Ignore them, maybe the'll go away. > I *am*, unfortunately, in > the business of fixing the mistakes made by inexpert C programmers. I wish > I weren't in that business. Are you sure? Why do you think they pay us those big bux? That ain't working, that's the way you do it.

The distinxion between short, int, & long, regarding portability is a subtle point which is learned over time.

I guess what I'm trying to say is mellow out. Many people respect you for your knowledge (including myself. We have had our differences, but I can see you know your stuff); don't blow it by yelling at novices. I used to annoy some of my coworkers about the way they coded. They just weren't interested in being taught. I'm sure you have better things to do. At least you get paid for fixing bugs. Who pays you to post? This was meant to be a friendly letter. I guess I didn't do very well. I am trying to put our differences to rest. Forgive my third comment. I guess I say too much of myself in you this time :-) Hey, is this net.wax.philosophic or what? Take care. jim cottrell@nbs */ ------
