c++ - 未声明的标识符？我以为我定义了

因此，我在约会类的成员函数中发生了一个未声明的标识符错误。我以为我在构造函数中初始化了这些变量，在初始化列表中初始化了date对象。但是这两个变量都不起作用。我只是有点困惑，为什么编译器会认为它是未声明的类型而不是变量。

谢谢。

#include<iostream>
#include <string>


using namespace std;

class Date{

public:
    Date(int month, int day, int year);

    int getMonth() const;
    int getDay() const;
    int getYear() const;

private:
    int month;
    int day;
    int year;
};

Date::Date(int month, int day, int year) {
    this->month = month;
    this->day = day;
    this->year = year;
}

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

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

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


class Appointment
{

    public:
    Appointment(string description, int month, int day, int year, int hour, int minute);
    virtual bool occurs_on(int month, int day, int year);

    private:
    int hour, minute;
    string convertInt(int number) const;
    virtual string print();

    protected:
    Date getDate();
    Date date;


};

Appointment::Appointment(string description, int month, int day, int year, int hour, int minute):date(month, day, year){
    // the above line, i'm trying to initalize the date object with the three parameters month day and year from the appointment constructor.
    this-> hour = hour;
    this-> minute =minute;

}

bool occurs_on(int month, int day, int year){
    if (date.getMonth()== month && date.getYear()= year && date.getDay()==day) //first error. variables like hour and minute from the constructor and date from the initalizer list are giving me unknown type name errors. I thought I initalized those variables in the constructor and in the initalizer list.

        day= minute; //

        return true;

}

最佳答案

您已经在Appointment::前面错过了occurs_on。

//---vvvvvvvvvvvvv
bool Appointment::occurs_on(int month, int day, int year){
    // ..
}
