C++ :: Lexing File Into Binary Search Tree

Standard example. I have a large text file and I wish to lex it into words. I tell the program that all words are delimited by ' ' ';' ':' and ''.

When I run the program it seems to be outputting the occurances of the letters and not the words. Im gobsmacked, I dont know what the hell is going on. Heres the function that lexes letters and not words. I want words dammit words!!

First youll see I define root node and point it to null; This forms the base of the BST. Then keep munching one character at a time until EOF reached. If the character is not a delimiter, assign it to "word" string, character by character. If it is a delimiter, take the so-far-constructed "word" and chuck it in the BST, then clear the word string through .clear().

Repeat until done. But its not working.

Code:

struct masternode* lexical_scanner(ifstream* inputfile) {
string word;
char c;
struct masternode* root = NULL;
while (c!=EOF){

[Code] .....

All the other functions in the source file are just fine, I've tested them in other apps and they are purpose built.
