How to access private data members outside the class without making "friend"s?

Asked 2011-07-16T11:54:46.427

I have a class A as mentioned below:-

class A{
     int iData;
};

I neither want to create member function nor inherit the above class A nor change the specifier of iData.

My doubts:-

How to access iData of an object say obj1 which is an instance of class A?
How to change or manipulate the iData of an object obj1?

Note: Don't use friend.

c++ class private encapsulation data-members

friend is your friend.

class A{
    friend void foo(A arg);
    int iData;
};

void foo(A arg){
     // can access a.iData here
}

If you're doing this regularly you should probably reconsider your design though.
