    Your ending braces don't match up properly. This is what you want
    Code:
    #include <iostream.h>
    
    class Inner
    { 
        int data;
    public:
        char id;
        void set (int x){ data= x;}
        Inner (int x): data(x) {}
    };
    
    class Outer
    { 
        Inner room;
    public:
        float (total);
        Outer (int, char);
        void set (int i, char id){
            room.set(i); // cannot do room.data = I;
            room.id =id;
        }
    };
    
    Outer::Outer (int i, char id): room(i)
    {room.id = id;}
    
    int main()
    { 
        Outer collect (10, 'A');
        collect.set(10, 'B'); // cannot do collect.room.id ='B' 
        collect.total = 0.01; // no problem with this
    }

    room.set(i); // cannot do room.data = I;
    That is because data is a private member of your Inner class.
    collect.set(10, 'B'); // cannot do collect.room.id ='B'
    Again, your room data member is declared to be private by default within the Outer class so you cannot access it directly from within the main function.

    Put everything under the public heading if you really need to do this.

Whereas owners of cats are compelled to realize that, if you provide them with food and water and shelter and affection, they draw the conclusion that they are gods."
