Project p21-4.exe raised exception class super with message 'Exception Object Address: 0x683446'.Process stopped. Use Step or Run to continue.
（上列訊息僅在Debugger設(shè)定核選Stop on C++ Exceptions才會出現(xiàn)）

程序執(zhí)行結(jié)果：
再編譯一次會輸出自定義的錯誤信息﹕
Please Input Two Number, x/y:
5
0
super constructor
這是自定義的錯誤信息，防止除數(shù)y等于0!!
按任意鍵繼續(xù)...
