operators overloading in c++ , I need to store words intead of a single letter?

[solina]

I need some help.

this is my function

 class teacher
{
    public:
    char  &operator[](int i);
    protected:
    char* contents;
};

.cpp

   char & teacher::operator[](int i) 
{
    return contents[i];
}

main

   teacher s1;
cout<<"Enter names: "<<endl;
cin>>s1[1];
cout<<s1[1];

If I enter a word, it only returns the first character, I don't know why if I'm using a char*

You are dereferencing the pointer.
However, I doubt that it points to something valid

struct person{
   std::string name;
};

person teacher;
std::cin >> teacher.name;
