Question

我的代码中有一些错误，我无法弄清楚如何修复它们。我试图谷歌类似的错误，但我无法解决我一直有的问题。

继承我的代码：

#include <iostream>

using namespace std;

class Date
{
private:
int year;
int month;
int day;

public:
    void setDay(int);
    void setMonth(int);
    void setYear(int);
    int getDay() const;
    int getMonth() const;
    int getYear() const;
    int getDate() const;

};


void Date::setDay(int d)
{
day = d;
}

void Date::setMonth(int m)
{
month = m;
}



void Date::setYear(int y)
{
year = y;
}


int Date::getDay() const;
{   
return day;
}



int Date::getMonth() const;
{
return month;
}

int Date::getYear() const;
{
return year;
}



int main() {

Date dat;
int datDay; //local variable for day
int datMon; //local variable for month
int datYea; //local variable for year

cout << "What is the day?";
cin >> datDay;

cout << "What is the month?";
cin >> datMon;

cout << "What is the year?";
cin >> datYea;

dat.setDay(datDay);
dat.setMonth(datMon);
dat.setYear(datYea);

//display
cout << "Day: " << dat.getDay() << endl;
cout << "Month: " << dat.getMonth() << endl;
cout << "Year: " << dat.getYear() << endl;
return 0;

}

这是我的错误：

Answer 1

就像尼尔在评论中所说的那样

int Date::getDay() const;
{   
return day;
}

应该是

int Date::getDay() const
{   
return day;
}

所以它也适用于getMonth和getYear

getDate的定义在哪里？

在C ++中用class预期的nonqualified-id错误？
