Help in my C++ program for removal of nodes from binary tree. Can I use the code:

void deallocateTree(course* p)

{

if (p==0) return;

delete p;

deallocateTree(p->yes);

deallocateTree(p->no);

}

or:

void deallocateTree(course* p) { if (!p) return; deallocateTree(p->yes); deallocateTree(p->no); delete p; }

Which one is better or they are the same? Thanks
