在重载的construcor中调用程序员定义的构造函数

Question

我试图在重载的3参数构造函数内部调用程序员定义的默认构造函数。当我创建Date类的实例时，将其传递3个参数，然后重载的构造函数会将这些参数传递给validate函数。如果返回值为false，我想在重载的构造函数中调用默认的构造函数，但会得到垃圾值。 1/-858993460/-858993460 可以在构造函数内调用构造函数吗？

//test.cpp

int main ()
{
    date d1(m, d, y);
}

//header
class Date {
private:
    string month;
    int day, year;
    bool validateDate(string, int, int);
    //Date();
public:
    Date();
    Date(string, int, int);
    void print(DateFormat type);
};

//implmentation
Date::Date() : month("January"), day(1), year(2001) { cout << "INSIDE CONST" << endl; } //default constructor

Date::Date(string m, int d, int y)  //overloaded constructor
{
    if (!validateDate(m, d, y))
    {
        cout << "IF FALSE" << endl;
        //Date(); //This doesn't work
        Date d1;  //This doesn't work as well
    }
    else
    {
        month = m;
        day = d;
        year = y;
        cout << "MONTH IS :" << month << " DAY IS: " << day << " YEAR IS: " << year << endl;
    }
}
