Dynamic, multi-dimensional pointers!

If you follow the pattern

Code:

thing = malloc ( N * sizeof *thing );

you need not worry about getting it correct.

So this

Code:

group_total = malloc (x * sizeof (long **));

becomes this

Code:

group_total = malloc (x * sizeof *group_total);

This

Code:

group_total[loop] = malloc (y * sizeof (long *));p

becomes this

Code:

group_total[loop] = malloc (y * sizeof *group_total[loop]);

And this

Code:

group_total[loop][loop2] = malloc (z * sizeof (long));

becomes

Code:

group_total[loop][loop2] = malloc (z * sizeof *group_total[loop][loop2]);

Then you can change **group_total to say double and have nothing to change but the declaration of group_total.

Thanks Dave!

And I appreciate your spelling it out for me too! :-)
