double Func(double x, double y)

{

{

throw new TException();

}

}

int WrapFunc()

{

Func(0, 0);

return 0;

}

int main()

{

try

{

WrapFunc();

}

catch (TException* e)

{

std::cout << "catch exception" << std::endl;

}

catch (...)//捕獲所有的異常

{

std::cout << "catch all exception" << std::endl;

}

return 0;

}

分析

當拋出new TException,catch語句必須是定義為指針，當拋出TException()對象的時候，catch語句必須是對象可以是catch(TException& e)或者catch(const TException& e)
