Hi, Sir, I program in C/C++ more than six years. It's not a problem for me to do this project. Also since it's a small project, it's a good chance for me to increase my credits. So I charge you the lowest price. Only one thing I'm confused is what you really want. The attachment you give us is exactly the implementation. You want it implemented as many functions, a class, or anything else. Please let me know what you exactly want. Then I'll do it very soon. Thanks for providing this chance. Best Regards Leonchen
