Using sentinel with binary search tree

[BoBok2002]

I am trying to build a binary search tree. The elements in my input file is printing, but with junk. The problem is with the sentinel in the while loop. I'm not sure of what else to try. I've tried:
while (infile)
while (count != 14 && infile.good())
while (strcmp(Str, sentinel) != 0)

But none of those are working. A sample of my input file is:
meel meet food copy home link hear seed read twig tree rain quiz push ride meel

And my current output file is:
copy food€'M hear homeÈ'M link meeth'M push quizp(M rainX(M read@(M ride seedø'M tree twig((M

Please help me figure out what is wrong. The code is below. Thanks.

void buildTree(TNODE *&Parent)
{
     char Str[5];
     TNODE *temp, *temp1, *newnode;
     int compVal;
     bool found;
     char sentinel[5];
     int count = 0;
     
     infile >> sentinel >> Str;
     
     Parent = NULL;
       
     while (strcmp(Str, sentinel) != 0)
     //while (count != 14 && infile.good())
     {
             //infile >> Str;
             
             newnode = new TNODE;
             strcpy(newnode -> dataStr, Str);
             newnode -> left = NULL;
             newnode -> right = NULL;
