调试时可以输进去数字，但到输出时显示内存错误了

Teacher_Cadre(int wage=0){}
初始化列表  初始化列表  怎么全是这个问题啊......

谢谢，终于成功了，这个动态分配的对了不知道那个数组为什么不对

你传递参数如果是数组的话  难道你要把数组中所有的元素都作为参数吗？

所以只要传递一个首地址就可以啦  

这个有bug程序想要表达的意思是什么，没表达有意义的结果。

#include<iostream>
using namespace std;
class Teacher
{
private:
    char *name;
    int age;
    char *title;
public:
    Teacher(char *name=0,int age=0,char *title=0)

    void get()

        title=new char[10];   
        cout<<"input name:"<<endl;
        cin>>name;
        cout<<"input age:"<<endl;
        cin>>age;
        cout<<"input title:"<<endl;
        cin>>title;
    };
    ~Teacher()
    {
        delete[] name;delete[] title;
    }
    void display()
    {
        cout<<"the name is:"<<name<<endl;
        cout<<"the age is:"<<age<<endl;
        cout<<"the title is:"<<title<<endl;
    }

};
class Cadre{

    Cadre(char *name=0,int age=0,char *post=0)

        post=new char[10];   
        cout<<"input name:"<<endl;
        cin>>name;
        cout<<"input age:"<<endl;
        cin>>age;
        cout<<"input postion:"<<endl;
        cin>>post;
    }
    ~Cadre(){delete[] name;delete[] post;}
    void display()
    {
     cout<<"the post is"<<post<<endl;
    }
private:
    char *name;
    int age;
    char *post;
};
class Teacher_Cadre:public Teacher,public Cadre
{
   private:   
    int wage;   
   public:
  Teacher_Cadre(int wage=0)
    {    }
    void show()
    {
    Teacher::display();
    }
   void getwage()
    {
    cout<<"input wage:"<<endl;
    cin>>wage;
    }
    void put()
    {
    cout<<"the wage is"<<wage<<endl;
    cout<<"the post is"<<endl;
      Cadre::display();
    }
};
int main()
{
Teacher_Cadre tc;
Teacher t1;
t1.get();
Cadre c1;
c1.get();
tc.getwage();
tc.Teacher::get();
tc.Cadre::get();
tc.show();
tc.put();
}
tc.show()没有初始化，增加初始化即可。而且，这段代码很混乱，建议LZ不要这种方法写。

这样错了但是像上面那样把name=new char[10];title=new char[10];写在get的函数体中就对了，是不是在构造函数中把name指向0了就不能再开辟空间了？   

因为形参名字与数据成员的名字相同了，如果改成 Teacher(char *name=0,int age=0,char *title=0){this->name=new char[10];就对了，可是系统都不看形参名为什么还不能和数据成员的名字相同
