Question

c++的问题在线求解答啊，急救啊

#include"iostream"
#include"string"
using namespace std;
class Time
{
protected:
int hours,minutes,sconds;
public:
Time(int h,int m,int s)
{
hours=h;
minutes=m;
sconds=s;
}
int display()
{
cout<<hours<<minutes<<sconds;
}
};
class Date
{
protected:
int month,day,year;
public:
Date(int a,int b,int c)
{
month=a;
day=b;
year=c;
}
public:
int display()
{
cout<<month<<day<<year;
}
};
class Birthtime:public Time,public Date
{
string Childname;
public:
Birthtime(int h,int m,int s,int a,int b,int c,string na):Time(h,m,s),Date(a,b,c)
{
Childname=na;
}
};
int main()
{
Birthtime axf(1,2,3,4,5,6,"asd");
cout<<axf.Time::display()<<endl;
cout<<axf.Date::display()<<endl;
}
显示怎么总在显示后面多一堆数啊，求指教啊，答对了保证追加分数啊

Answer 1

cout<<axf.Time::display()<<endl;
cout<<axf.Date::display()<<endl;
改成
axf.Time::display()
axf.Date::display()试试吧。

Answer 2

#include"iostream"
#include"string"
using namespace std;
class Time
{
protected:
int hours,minutes,sconds;
public:
Time(int h,int m,int s)
{
hours=h;
minutes=m;
sconds=s;
}
int display()
{
cout<<hours<<minutes<<sconds;
return 0;
}
};
class Date
{
protected:
int month,day,year;
public:
Date(int a,int b,int c)
{
month=a;
day=b;
year=c;
}
public:
int display()
{
cout<<month<<day<<year;
return 0;
}
};
class Birthtime:public Time,public Date
{
string Childname;
public:
Birthtime(int h,int m,int s,int a,int b,int c,string na):Time(h,m,s),Date(a,b,c)
{
Childname=na;
}
};
int main()
{
Birthtime axf(1,2,3,4,5,6,"asd");
cout<<axf.Time::display()<<endl;
cout<<axf.Date::display()<<endl;
}

Output:
