C++ Binary Tree : Error Creating Special Binary Tree

Main.cpp

using namespace std; covo AWNA Bint main() { bt morseTree; return 0;\" v:shapes=\"Picture_x0020_199\">

bt.h

#include using namespace std; class bt { private: struct node { node* left; node* right; string m\" v:shapes=\"Picture_x0020_200\">

bt.cpp ( error )

Note : Line 22 is ... else if (strVariable[i] == '_') {

morseTable.txt

I'm trying to create a binary tree of depth four. Once that is created, I iterate through each line in morseTable.txt and (ideally) maneuver through the tree, as it shows in bt.cpp. Once I reach the end of maneuvering it's supposed to assign those values accordingly. However, there's an error along the way of this displayed in bt.cpp. Is anyone capable of finding where this is going wrong so I can successfully (hopefully continue) to create the tree displayed below?

Thank you
