Class encapsulation problem
Hi ! I'm having some trouble understanding class encapsulation on the following example (I don't think the rest of the source is relevant) . So I have a trivial Time class (from a C++ book) with two integers (minutes and hours) as private and all the member functions public .
Why is it possible for an object to access other object's private members ? Thank you .
Time Time::Sum(const Time & t) const { Time sum; sum.minutes = minutes + t.minutes; sum.hours = hours + t.hours + sum.minutes / 60; sum.minutes %= 60; return sum; } |

Private members are accessible within the class and its friends
Since an object is part of the class, it can access them
Since an object is part of the class, it can access them
