#include "stdio.h"
class Reader{
private:
  char Name;
  int ID;
  char Priority;
public:
    Reader(char* x="",int y=0,char* z=""){Name=*x;ID=y;Priority=*z;}
    char GetName(){return Name;}
    int  GetID(){return ID;}
    char GetPriority(){return Priority;}
};
void main()
{
    Reader reader1("小明",2014110131,"学生");
    printf("%c\n%ld\n%c\n",reader1.GetName(),reader1.GetID(),reader1.GetPriority());
}
结果是
?
2014110131
?
求教下哪里错了

#include "stdio.h"
class Reader{
private:
  char Name;
  int ID;
  char Priority;
public:
    Reader(char* x="",int y=0,char* z=""){Name=*x;ID=y;Priority=*z;}
    char GetName(){return Name;}
    int  GetID(){return ID;}
    char GetPriority(){return Priority;}
};
void main()
{
    Reader reader1("小明",2014110131,"学生");
    printf("%c\n%ld\n%c\n",reader1.GetName(),reader1.GetID(),reader1.GetPriority());
}

PS：红色字体

申明的有问题吗？

Reader reader1("小明",2014110131,"学生")


“小明”和“学生”一个单位够用嘛？

哦哦  那我改成CString 的话还需要改动什么地方

麻烦版主帮我改改我刚学

//reader.h

#ifndef READER_H_
#define READER_H_

class Reader{
private:
    std::string Name;
    std::string Priority;
    int Id;
public:
    Reader();
    Reader(const std::string & na, const std::string & pr, int id);
    ~Reader();
    void Show() const;
};
#endif

//reader.cpp

#include <iostream>
#include <string>
#include "reader.h"

Reader::Reader()
{
    Name = "";
    Priority = "";
    Id = 0;
}

Reader::Reader(const std::string & na, const std::string & pr, int id)
{
    Name = na;
    Priority = pr;
    Id = id;
}

Reader::~Reader()
{

}

void Reader::Show() const
{
    using std::cout;
    using std::endl;
    cout << "姓名：" << Name << endl;
    cout << "ID  ：" << Id << endl;
    cout << "备注：" << Priority << endl;
}

//usread.cpp

#include <iostream>
#include "reader.h"

int main()
{
    Reader number_a("小明","学生",2014110131);
    number_a.Show();

    system("pause");
    return 0;
}

谢谢版主

#include "stdio.h"
class Reader{
private:
  char Name[10];
  int ID;
  char Priority[10];
public:
    Reader(char* x="",int y=0,char* z=""){Name=*x;ID=y;Priority=*z;}
    char GetName(){return Name;}
    int  GetID(){return ID;}
    char GetPriority(){return Priority;}
};
void main()
{
    Reader reader1("小明",2014110131,"学生");
    printf("%c\n%ld\n%c\n",reader1.GetName(),reader1.GetID(),reader1.GetPriority());
}要把Name/Priority定义成字符数组
