"One convention that we have is to use the names of fruits and vegetables for variables (only in small
code fragments, not in any real program, of course):
char pear[40];
double peach;
int mango = 13;
long melon = 2001;
This makes it easy to tell what's a C reserved word, and what's a name the programmer supplied.
Some people say that you can't compare apples and oranges, but why not—they are both hand-held
round edible things that grow on trees. Once you get used to it, the fruit loops really seem to help.
There is one other convention—sometimes we repeat a key point to emphasize it. In addition, we
sometimes repeat a key point to emphasize it."
