RE: Increment and decrement operators

["Glenn Howald" <ghowald@xxxxxxxxxx>]

My suggestion would be to try it with an example.

a[] = {0, 0, 0, 0};
i = 0;

after this one, a[] = {1, 0, 0, 0}, i=1 because i is incremented after the
operation.

> a[i++]=a[i++] + 1;
after this one, a[] = {0, 1, 0, 0}, i=2 because i is incremented after the
right side of the assignment is evaluated and then again after the left side
is evaluated.

I may get flamed because I didn't actually have a computer do it, but this
is my understanding of the issue. In a nutshell, the second statement has 2
increments on the variable i.
