[Paul Akkermans]

Hi group,   I have constructed the following code: ----------------------------------------------------------------------------------------------------------------------------- #include "TreeElement.h"   struct node  { TreeElementType elt;    struct node *left, *right;  }; typedef struct node Node;   typedef Node *Tree;   /* Tree Type. */ ---------------------------------------------------------------------------------------------------------------------------- typedef char TreeElementType[11];   #define TreeElementLess(e1, e2) (strcmp(e1,e2) < 0)         /* i.e.  e1 < e2 */   #define TreeElementMove(e1, e2) (strncpy(*e2, e1, 10))         /* i.e.  e2=e1 */   /* Define Tree of Short Alphanumeric Strings */ ---------------------------------------------------------------------------------------------------------------------------   #include <stdio.h> #include "tree.h"   void WriteTreeSlave( Tree T, int indent )                         /*L.Allison*/ /* Write a tree, with root at the LHS, by a right-to-left, infix traversal */  { int i;  char str[]="----------|";      if( T != NULL )     { WriteTreeSlave(T->right, indent+1);         for(i=0; i < indent; i++) printf("          |");       sprintf(str, "%s", T->elt);      /* NB. assumed to be a Tree of String */       i = 0;       while( str[i] != NULL ) i++;       while( i < 10 ) { str[i]='-'; i++; }       str[i] = '|'; str[i+1] = NULL;       printf("%s\n", str);         WriteTreeSlave(T->left, indent+1);     }  }/*WriteTreeSlave*/   void WriteTree( Tree T ) { WriteTreeSlave(T, 0); }   /* Write a Tree down the page. */   int main (){  WriteTreeSlave("paul",0);  } --------------------------------------------------------------------------------------------------------------------------------------------------------------------- It is my goal to call the function "WriteTreeSlave(?,?)"  but I don't know what variables I have to give along with this function (that's why I placed the ?-mark there) . Ik have tried ("paul",0); but that doesn´t work. Can anybody help me?   Thanks in advance,   Paul Akkermans
