hehe i think i figured out what my problem was *blush* i was correctly creating the array and it was null, if you look at the create array i was just creating a tempory array

hmmmm okay

So arrayPtr is a pointer that points to and array of pointers;
So if wanted to change one of the pointers in the array,
i though i could just do arrayPtr[index] = NewPointer;
but...

Ahh good point,

i think is where i confused with pointers to pointers,

If i do retVal = *arrayPtr;

That means retval equals the pointer that arrayPtr was pointing to right?

so that means...

Hi guys, im trying to make a Dynamic Mutli dimensional Array,

There are lots of tutorials for making these (using a pointer array of poniters) but not for adding and retriving from them really.

Ahhh cool, should of thought of that.. i think ill go with option one... Thanks for the help.

Oh i just noticed i have

convertString2Decimal

Hehe whoops yeah sorry forgot to fix that.



int main(int argc, char **argv)
{
if(argc == 2)
{

OpenWriteFileFromTree(argv[1],BTRoot);

Oh and ive been fooling around with this for a while trying to get it work. So there might be some usless stuff in there (inculdes i dont need, printf's i dont ect...) sorry. =)

Hi guys,

Cool, thanks for all the help guys. I got it figured out =). I used a binary tree in the end (thanks bob i nicked your btree code, dont worry i did read the binary tree chapter and understood it).
