关于runtime_error的问题

按照c++ primer上的程序,
if (argc != 3)
throw runtime_error("wrong number of arguments");
我故意把参数输入不是三个,然后应该抛出异常wrong number of arguments,但是我却是程序中断，显示
This application has requested the Runtime to terminate it in an unusual way.

你又没捕获异常

还是你使用了set_terminate或set_unexpected，但程序没调用你设置的函数？

你这样当然中断了，异常在try/catch中捕获

catch(const runtime_error &err)

If no matching catch is found, then the program calls the library terminate function.Usually,terminate call the library function abort to exit the program.

An exception cannot remain unhandled. An exception is an important enough event that the program cannot continue executing normally. If no matching catch is found, then the program calls the library terminate function.Usually,terminate call the library function abort to exit the program.

自己抛出的异常，被自己接收，但是楼主没有自己对异常进行处理！那就会按照系统自己定义的方式进行处理！

应该再tyr|catch里。
