I need help with a program that is supposed to take data on football players from a txt file and place them in a binary search tree then use case statements to t osearch the tree inorder, preorder and postorder recursively
here's what i got so far

/* This program reads football statistics of players on the Chicago Bears from a
text files and disblay the desired information via a numbered menu system.
*/
#include<stdio.h>
#include<string.h>
# define TYPED_ALLOC(type) (type *)malloc(sizeof (type)
/* define player structure */
typedef struct player
{
char team[3];
int number, passyards, rushyards, recpyards, passTD, rushTD, recpTD, receptions;
char fname[30];
char lname[30];
char pos[4];
char wname[60];
} playerdata;
typedef struct tree_node_s
{
char key;
struct tree_node_s *leftptr, *rightptr;
} tree_node_t;
void *tree_insert(tree_node_t *rootp , char new_key);
void tree_inorder(tree_node_t *rootp);
int
main(void)
{
FILE *fptr;
tree_node_t *bstreep; /* Binary Search Tree */
playerdata data_key;
bstreep = NULL;
if ((fptr = fopen("C:/Documents and Settings/Owner/Desktop/Jason/C programing/assignment6/assignment6data.txt", "r")) == NULL)
{ printf("Error: the file cannot be opened\n");
}
else
fscanf(fptr, "%s %s %s %s %s", &data_key.team, &data_key.number,
&data_key.fname, &data_key.lname);
strcpy(data_key.wname, data_key.lname);
strcat(data_key.wname, ", ");
strcat(data_key.wname, data_key.fname);
bstreep = tree_insert(bstreep, data_key.wname);
}
/* Fill Search tree */
tree_node_t *treeinsert(tree_node_t *rootp, char new_key)
{
if (rootp==NULL)
{
rootp = TYPED_ALLOC(tree_node_t);
strcpy(rootp->key,new_key);
rootp->leftp = NULL;
rootp_>rightp = NULL
}
else if (new_key == rootp->key)
{
}
/* Insert in left subtree */
else if (strcmp(new_key ,rootp->key))<0)
{
rootp->leftp = treeinsert(rootp->leftp, new_key);
} /* End Insert */
/* Insert in right subtree */
else
{
rootp->rightp = treeinsert(rootp->rightp, new_key);
} /* End Insert */
return (rootp);
}
/* End treeinsert */i keep getting an error when calling the treeinsert function that says
51 C:\Documents and Settings\Owner\My Documents\BRADLEY\Programming C\Brad Project 9\Brad assign 9.c [Warning] passing arg 2 of `tree_insert' makes integer from pointer without a cast
which doesn't make sense because the function only uses characters
someone please help me out
