C++ access specifiers

Question

I just want to make sure I got the idea of public and private right.

Regarding the private access specifier, does it mean:

• Only accessed inside the class
• Cannot be accessed from the object of the class unless there are public class methods that can be used to access them (Can other objects use those public functions?)
• No other object can access them

And for public:

• Accessed from the object of the class
• Accessed from any other object

Is that right?
