Is there an error in this code?

[sesslit805]

Hello all! I am studying for my midterm and I went through my profs powerpoint and she asked if there is anything wrong with this code:

Any problem with this
code segment?
A) Yes
B) No

class Date {
private:
int m_year, m_month, m_day;
public:
Date(int year, int month, int day)
{ setDate(year, month, day); }
void setDate(int year, int month, int day)
{ m_year = year;
m_month = month;
m_day = day;
}
int getYear() { return m_year; }
int getMonth() { return m_month; }
int getDay() { return m_day; }
};

// Pass date by const reference to avoid making a copy of date
void printDate(const Date &date)
{ cout<<date.getYear()<<"/"<<date.getMonth()<<"/"<<date.getDay(); }
int main()
{ Date date(2016, 10, 16);
printDate(date);
return 0;
}

I cant really find anything except the constructor looks funky. But can someone catch something and why is it wrong? thank you my friends!

Try to compile it and then see if there are any problems.

getYear(), getMonth() and getDate() must be declared const if you want to use them with a const object.
That's what you try to do here:
cout<<date.getYear()<<"/"<<date.getMonth()<<"/"<<date.getDay();
date is declared const (const Date &date)
