さようなら

Life is just like a main routine in C/C++.

As soon as we were born, the prototype was defined in a header file.

To live is to write the function.

But sometimes we have to invoke a subroutine, in the worst case, we run into a dead loop.

Now I want to break the loop. however it may return NULL.

Thus, it's real time to say goodbye to the subroutine.

Girl, goodbye to you.
