c++ 字符数组

创建一个employee类，该类中用字符数组表示姓名、街道地址、市、省和邮政编码。把构造函数、changname()、display()的函数的原型放在类定义中，函数实现放在类外。构造函数初始化每个成员，changname()可以让用户修改姓名，display()函数把完整的对象数据打印出来。主函数中建立两个对象测试一下

追问：我在你的代码上做了修改，为什么postnum出来一堆“烫”呢？求解释
#include<iostream>
using namespace std;
class Employee
{
private:
   char name[20];
   char address[100];
   char city[15];
   char province[15];
   char postnum[20];
public:
   Employee(char *name,char *address,char *city,char *province,char *postname);
   void changename();
   void display();
};
Employee::Employee(char *name,char *address,char *city,char *province,char *postname)
{
    strcpy(this->name,name);
strcpy(this->address,address);
strcpy(this->city,city);
strcpy(this->province,province);
strcpy(this->postnum,postnum);
}
void Employee::changename()
{char name1[20];
cout<<"修改姓名："<<endl;
cin>>*name1;
strcpy(this->name,name1);
}
void Employee::display()
{
    cout<<name<<endl;
    cout<<address<<endl;
cout<<city<<endl;
cout<<province<<endl;
cout<<postnum<<endl;
}
int main()
{ Employee a("ssss","aa","cc","ddd","dsd");
 a.display();
 a.changename();
 a.display();
  return 0;
} 

答案：
#include<iostream>
using namespace std;
class Employee
{
private:
   char name[20];
   char address[100];
   char city[15];
   char province[15];
   char postnum[10];
public:
   Employee(char *name,char *address,char *city,char *province,char *postname);
   void changename();
   void display();
};
Employee::Employee(char *name,char *address,char *city,char *province,char *postname)
{
    strcpy(this->name,name);
strcpy(this->address,address);
strcpy(this->city,city);
strcpy(this->province,province);
strcpy(this->postnum,postnum);
}
void Employee::changename()
{
    char name1[20];
strcpy(name1,name);
}
void Employee::display()
{
    cout<<name<<endl;
    cout<<address<<endl;
cout<<city<<endl;
cout<<province<<endl;
cout<<postnum<<endl;
}
int main()
{
    return 0;
}
