Practice
  Create a tree, which has h (h>0) layers, and its each node has w(w>0) se complete the following incomplete solution.
  #include <stdlib.h>
  #include <string.h>
  struct tree{
  char info;
  p_sub; //link to sub-nodes};
  // allocate memory and initiate
  void dnode ( struct tree* tmp )
  {
  = malloc( sizeof (struct tree) );
  = 0x41;
  = NULL;
  }
  struct tree *dtree (struct tree* subtree, int height, int width)
  {
  int i;
  if ( !subtree ) //if necessary, allocte memory for subtree
  denode(subtree);
  if ( height == 1 )
  return subtree;
  else if ( height == 2 ) {
  struct tree *leaf = NULL;
  for ( i=0; i<width; i++ ) {
  denode ( );
  ;
  leaf = NULL;}
  return subtree;}
  else {
  for ( i=0; i<width; i++ ) {
  }
  return subtree;
  }
  }
  main()
  {
  .........
  struct tree *root = NULL;
