C++异常处理（二）----声明接口

• 接口声明的三种形式
• 抛出一切形式的异常

void freeobj(mycoach &t)
{
    if (t.age < )
    {
        cout <<"精神可嘉~但还是年龄太小" <<endl;
        throw t.age;
    }
    if (t.months <= )
    {
        cout << "精神可嘉~再练一段时间，加油" << endl;
        throw t.months;
    }
    //throw t;
}

• 抛出指定形式的异常

void freeobj(mycoach &t) throw(int, char,char*)
{
    if (t.age < )
    {
        cout <<"精神可嘉~但还是年龄太小" <<endl;
        throw t.age;
    }
    if (t.months <= )
    {
        cout << "精神可嘉~再练一段时间，加油" << endl;
        throw t.months;
    }
    //throw t;
}

• 不抛异常

void freeobj(mycoach &t) throw()
{
    if (t.age < )
    {
        cout <<"精神可嘉~但还是年龄太小" <<endl;
        throw t.age;
    }
    if (t.months <= )
    {
        cout << "精神可嘉~再练一段时间，加油" << endl;
        throw t.months;
    }
    //throw t;
}
