  K&R Ex 1-3         


Author: Gio
Date: Apr 19, 2008 15:36

I'm reading the K&R book and doing the exercises. Currently, I'm working
on Exercise 1-3.

Here's what I have:

[code]

#include

main()
{
float fahr, celsius;
float lower, upper, step;

lower = 0; /* lower limit of temperatuire scale */
upper = 300; /* upper limit */
step = 20; /* step size */
fahr = lower;

  A trick question

[code]

short i, j;

i = -32768;
j = -i;

printf("%%d", j);

[/code]

As some of you may have guessed by my previous post (about books), I'm
trying to learn C. Well, a friend of mine (who is a programmer) asked me
(who is not a programmer) what the output of this would be, and why. I
had no clue, so I ran it, and it printed -32768. I gave him my best
guess (which was wrong):
> 1) a short maxes out at 32768, so it has no more room to hold the
