Help me to resolve undefined reference

[Ku Cheng]

It does work, if it is a c program. However if I change it to C++ program, 
it does not link in my environment. I have attach the C++ version. Could 
you try it and let me know. If it works in your machine, it must have 
something to do with my environment.

Thanks for your help again.
