Dear Tzahi,
I think that's the problem is that you can't delete members from an array --
even if it was created dynamically, because the memory allocation here is
allocated continuously as an ordinary static array -- (the created dynamic
memory you issued is an array for every thing). You can
On the same subject, can someone please explain a bit about the free()
function ? what does it do, and how come you can only send it the memory
address which you started allocating from ?

Thanks for the answers :-)

letGoOfMemory(pointer-1,*(pointer-1));
}
do i understand correctly?

how come? he is refering to memory which is not allocated? lets ignore
