Как реализовать класс Dictionary?

#include <iostream>
#include <cstdio>
#include <conio.h>
using namespace std;
struct WordCard
{
       char *word;
       char *trans;
};  
class Dictionary
{
      public:
      char name[];
      struct WordCard card[100];
      friend istream &operator>>(istream &stream, Dictionary &ob);
      Dictionary(char n[]);
      void greate();
      void show();
      Dictionary operator+(Dictionary ob);
      Dictionary operator-(Dictionary ob);
      Dictionary operator/(Dictionary ob);
};    
Dictionary::Dictionary(char n[])
{     
 strcpy(this->name,n);
}     
istream &operator>>(istream &stream, Dictionary &ob)
{     
cout << "Enter the name of your new dictionary:"<<endl;
stream >> ob.name;
}
 
void Dictionary::greate()
{
 
 
     cout<<"Enter name of your new dictionary"<<endl;
     cin>>name;
 
}
 
void Dictionary::show()
{
     cout<<"Your Dictionaries:"<<endl;
     cout<<name<<":"<<endl;
 }
int main()
{
char ch;
Dictionary d("MAth");
Dictionary a("Dictionary");
Dictionary b("FREEEEEE");
 for(;;)
     {
     cout<<"Dictionary builder:\n";
     cout<<"1.Greate new dictionary\n";
     cout<<"2.Show dictionaries\n";
     cout<<"3.Exit\n";     
     cout<<"Your choise: ";
     cin>>ch; 
     switch(ch)
   {
     case '1':a.greate();break;
     case '2':a.show(); break;
     case '3':exit(0);
}
}
return 0;
}
