C ++重載成員函數錯誤

Question

您好，我正在制作一個具有3個類的程序，當我使用成員初始化列表時，出現一個錯誤，提示“沒有重載函數“ people :: people”的實例與指定的類型匹配：

MAIN.cpp

    #include <iostream>
    #include "conio.h"
    #include <string>
    #include "birthday.h"
    #include "people.h"
    using namespace std;

    void main(){
        birthday birthObj (30, 06, 1987);

        people me("The King",birthObj);
        _getch();
    }

生日

    #pragma once
    class birthday
    {
    public:
birthday(int d, int m, int y);
        void printdate();
    private:
        int month;
        int day;
        int year;
    };

BIRTHDAY.cpp

    #include "birthday.h"
    #include <iostream>
    #include "conio.h"
    #include <string>

    using namespace std;

    birthday::birthday(int d, int m, int y)
    {
        month = m;
        day = d;
        year = y;
    }
    void birthday::printdate()
    {
        cout << day << "/" << month << "/" << year;
    }

人

    #pragma once
    #include <iostream>
    #include "conio.h"
    #include <string>
    #include "birthday.h"
    using namespace std;

    class people
    {
    public:
        people(string x, birthday bo);
        void printInfo();
    private:
        string name;
        birthday dateOfBirth;
    };

人.cpp

    #include "people.h"
    #include <iostream>
    #include "conio.h"
    #include <string>
    #include "birthday.h"
    using namespace std;

    people::people()
    : name(x), dateOfBirth(bo)
    {
    }

    void people::printInfo()
    {
        cout << name << " was born on ";
        dateOfBirth.printdate(); 
    }

Answer 1

People.cpp應該是：

people::people(string x, birthday bo) : name(x), dateOfBirth(bo) { } 

Answer 2

您尚未實現people(string x, birthday bo); 構造函數。 在您的PEOPLE.cpp中，更改

people::people()
    : name(x), dateOfBirth(bo)

至

people::people(string x, birthday bo)
    : name(x), dateOfBirth(bo)

Answer 3

您在PEOPLE.cpp中的構造函數具有錯誤的簽名：

應該

people :: people（字符串x，生日bo）

代替

人::人（）

Answer 4

 people::people()
: name(x), dateOfBirth(bo)
{
}

您已經忘記了此構造函數的參數。

Answer 5

poeple ctor聲明和定義不匹配！
