你的程序问题太多了，首先是类声明就错了，class的c要小写，子类不能访问父类成员，想访问要声明为友元，还有你对对于给私有成员赋值的方法没弄清，都写反了

你这不是C++，C++不是这样

#include <iostream>
#include <iomanip>

class Date
{
public:
    Date( int year, int month, int day ) : year_(year), month_(month), day_(day)
    {
    }
private:
    int year_, month_, day_;
    friend std::ostream& operator<<( std::ostream&, const Date& );
};
std::ostream& operator<<( std::ostream& os, const Date& date )
{
    std::ostream::char_type c = os.fill();
    os.fill( '0' );
    os << std::setw(4) << date.year_
       << '-' << std::setw(2) << date.month_
       << '-' << std::setw(2) << date.day_;
    os.fill( c );
    return os;
}

class Time
{
public:
    Time( int hour, int minute, int second ) : hour_(hour), minute_(minute), second_(second)
    {
    }
private:
    int hour_, minute_, second_;
    friend std::ostream& operator<<( std::ostream&, const Time& );
};
std::ostream& operator<<( std::ostream& os, const Time& time )
{
    std::ostream::char_type c = os.fill();
    os.fill( '0' );
    os << std::setw(2) << time.hour_
       << ':' << std::setw(2) << time.minute_
       << ':' << std::setw(2) << time.second_;
    os.fill( c );
    return os;
}

class Week : public Date, public Time
{
public:
    enum DayOfWeek{ Sun, Mon, Tue, Wed, Thu, Fri, Sat };
    Week( int year, int month, int day, int hour, int minute, int second, DayOfWeek dow ) : Date(year,month,day), Time(hour,minute,second), dayofweek_(dow)
    {
    }
private:
    DayOfWeek dayofweek_;
    friend std::ostream& operator<<( std::ostream&, const Week& );
};
std::ostream& operator<<( std::ostream& os, const Week& week )
{
    static const char* names_[] = { "Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat" };
    os << (const Date&)week << ' ' << (const Time&)week << ' ' << names_[week.dayofweek_];
    return os;
}

using namespace std;

int main( void )
{
    Week week( 2015,11,12, 9,1,30, Week::Thu );
    cout << week << endl;

    return 0;
}

输出

看不懂，帮你顶上去
