max function should be defined/declared before usage.

If not the function, atleast it's prototype.

int max(int a, int b);

Lol, the problem is here:

if(root=NULL)
	return 0;

This is an assignment operation. What you really want, is this:

if(root == NULL)
	return 0;

if the question means it will show wrong answer then the problem is with if(root=NULL)
and if it means compiler error then..there wil be no compiler error...it will successfully compiled..in c we dont need to declare a function before using it;
