omer,

Your code cuts off at line 417.

Regardless of that, what's your specific problem?

Are you really expecting us to compile your program and find the error for ourselves?

[weaknessforcats]

Also, you are using very old C++ header files. iostream.h is pre-1998 C++. That is, non-ANS C++.

I couldn't compile your code if I wanted becuse of these old and obsolete headers.
