Question

嗨，我正在制作一个包含3个类的程序，当我使用成员初始化列表时，我收到一条错误，说“没有重载函数的实例”people :: people“匹配指定的类型：

的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();
    }

BIRTHDAY.h

    #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;
    }

PEOPLE.h

    #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;
    };

PEOPLE.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应该是：

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

Answer 2

PEOPLE.cpp中的构造函数具有错误的签名：

应该是

people :: people（string x，birthday bo）

而不是

人::人（）

Answer 3

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

你忘记了这个构造函数的参数。

Answer 4

您没有实现people(string x, birthday bo);构造函数。在你的PEOPLE.cpp中，改变

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

到

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

Answer 5

poeple ctor声明和定义不匹配！

C ++重载成员函数错误
