If someone can tell me why my program crash

See my edited post. Secondly, if you're just learning C++, why are you using a third-party library to learn from? You should be learning from books, tutorials, etc.

The MySQL library assumes you know C++ already, so when you use the library, you know exactly what you're doing. Otherwise, all you will be doing is writing apps that are full of mistakes, memory leaks, etc.
