Thanks for the help, it helped me undestand alot.

I need to dynamicly allocate a 2 dimensional array in a function.
The parameters that are passed to the function are the columns and rows of the matrix.(Do i use malloc, calloc, new...)?

The function has to be recursive and when I call the function from inside the function i'll have to write:
avgL=AverageOfValues(root->left, &num_of_nodesL);
and from what I understand you can't do...

I have a function that its prototype is:

float AverageOfValues(TNODE *root, int *amm_of_nodes);
I know that, unlike in C++, in C you cant pass variables by-refrence (&var),
My question is how...

thanks salem it worked!!

Pleeaase help,

Can anyone give me an idea of how i can write a program that makes a binary tree so that i can test other programs that work with binary trees?

Can someone explain to me about passing 2 dimensional arrays to functions.
To bemore specific:
