If we have a paper width of 8.5 inches and use 1 inch for margins (1/2 inch each side), how much usable space do we have left? Anyone can see that the result is 7.5 inches. But this program sees things differently. What's happening?
1 /************************************************
2 * paper_size -- Find the usable width on *
3 * a page. *
4 ************************************************/
5 #define PAPER_WIDTH 8.5; // Width of the page
6 #define MARGIN 1.0; // Total margins
7 // Usable space on the page
8 #define USABLE PAPER_WIDTH -MARGIN;
9
10 #include <iostream>
11
12 int main()
13 {
14 // The usable width
15 double text_width = USABLE;
16
17 std::cout << "Text width is " <<
18 text_width << '\n';
19 return (0);
20 }

In my off-hours, I ported the game Adventure to the company computer and spent more than a few odd hours playing my game. One morning my manager called me into his office.
"Did you put Adventure on the system?" he asked.
"I did it my off-hours," I replied.
"Oh, I'm not criticizing you," he assured me. "As a matter of fact, I want to commend you. Ever since this project began, we've had daily visits from Bill (the head of marketing). Every day he comes in, plays with the software, and then insists on changes. But in the past week, he's spent all his time playing Adventure, giving him no time to make change requests. I just wanted to thank you for keeping him out of my hair."
