[I just got this one a few days ago.]
(Gothic News Service, 3/10/03) Early Sunday morning visitors to Mount Rushmore reported that they were astonished to find they could not look up the 5,725-foot mountain and see the 60-foot high carved stone heads of U.S Presidents George Washington, Thomas Jefferson, Theodore Roosevelt, and Abraham Lincoln. Instead, they found themselves looking at a large painted portrait of President Bush hanging upside down on a cable stretched several hundred feet between the barely exposed foreheads of Lincoln and Washington.
Visitors reported that not only was the painted Bush upside down, but that his bright red cheeks and much ruffled dark hair indicated signs of considerable shaking, an effect that was amplified by the canvas rippling in the early March wind. Indeed it appeared had been picked him up by his feet and held him hanging down while the portrait was in progress.
"Drop The Thought" - the visitor went on to report - was painted in large block letters across the top of the canvas which hung down at least 60 feet to cover the sight of the other Presidential faces.
Before News reporters could be called to the scene, two what looked like Park Service or Military helicopters arrived to lift the cable and canvas from the Monument. "That was also quite something," a visitor reported. "The canvas shook terribly when they lifted Bush
It was hard to find much other information. Mount Rushmore ? carved over a period of 14 years by sculptor Gutzon Borglum - was created to embody the spirit of the foundation, preservation, and expansion of the United States. Tight lipped, The National Park Service said it did not have any information on the perpetrators of the morning
"At a time when the country and the President most need the support of the American people," Ari Fleischer at the White House was reported to have said, "It is disturbing to hear that there are individuals out there who will abuse an historic Monument that represents our nation
This back and forth is an important concept to understand in C programming, especially on the Mac's RISC architecture. Almost every variable you work with can be represented in 32 bits of memory: thirty-two 1s and 0s define the data that a simple variable can hold. There are exceptions, like on the new 64-bit G5s and in the 128-bit world of AltiVec

That's the obvious one. But the second variable is a pointer to the first one, and it exists on the Stack. This variable is the one that's really called favoriteNumber, and it's the one we're working with. It is important to remember that there are now two parts to our simple variable, one of which exists in each world. This kind of division is common is C, but omnipresent in Cocoa. When you start making objects, Cocoa makes them all in the Heap because the Stack isn't big enough to hold them. In Cocoa, you deal with objects through pointers everywhere and are actually forbidden from dealing with them directly.
Posted by: Justinian on January 19, 2004 01:18 AMTo address this issue, we turn to the second place to put variables, which is called the Heap. If you think of the Stack as a high-rise apartment building somewhere, variables as tenets and each level building atop the one before it, then the Heap is the suburban sprawl, every citizen finding a space for herself, each lot a different size and locations that can't be readily predictable. For all the simplicity offered by the Stack, the Heap seems positively chaotic, but the reality is that each just obeys its own rules.
Posted by: Jucentius on January 19, 2004 01:18 AMThe Stack is just what it sounds like: a tower of things that starts at the bottom and builds upward as it goes. In our case, the things in the stack are called "Stack Frames" or just "frames". We start with one stack frame at the very bottom, and we build up from there.

Now we'll start working within the main function, where favoriteNumber is declared and used. The first thing we need to do is change how we declare the variable. Instead of
