遇到除0就抛异常的代码

double Division(int a, int b)
{
	if (b == 0)
		throw "Division by zero condition!";
	else
		return ((double)a / (double)b);
}

void Func()
{
	int len, time;
	cin >> len >> time;
	cout << Division(len, time) << endl;
}

int main()
{
	try
	{
		Func();
	}
	catch (const char* errmsg)
	{
		cout << errmsg << endl;
	}
}
