Hey, the guy who said to ask this on comp.lang.c is only 50%
correct. This is FAQ item!

But anyway, not true in all cases. In other words, if you see this in a program:

   a[i][j]

you don't really know if it means reference a vector of vectors or not.

It all depends on how a was declared. If char a[][], or char **a, that
is one thing.

But, it may also have been declared char a[5][10]. In which case
the resulting memory operations are more like what you would expect from
FORTRAN. Not two memory references but one.

The is one of the funky things about the C programming language.
