"register int i" is merely an optimization, you can safely use "int
i" instead. The "register" keyword only tells the compiler to
Thank you very much for the answer. As a general
principle, when and why should I register the
counters? Should I do the same in matrices or other
parameters that I pass and alter in the main body of
the C function?
Thanks again,

Berwin thanks, I tried that, but it didn't work. There
is a conflict in using a pointer for the operation
defined in the #define. The error message is:

Suppose that I use pointers for n and m. What should I
alter in the program in order f

Hope this helps.
