A structure is a special case of a class. The main difference is that all members of a struct are accessible as 'public' by default, whereas in the case of a class, it's 'private'. See also http://en.wikipedia.org/wiki/C++_classes#Differences_between_struct_and_classes_in_C++ - they also add that this is the only difference, which I forgor to mention ;o)

Don't get this.

>>> are these home/course work questions
No, I'm a C programming language teacher, and I want to learn C++ by asking simple questions. Ability to answer to simple questions tells us who is an expert and who is not.

Additional question:
Is the any difference between struct in C and struct in C++?

Is Your Active Directory as Secure as You Think?

More than 75% of all records are compromised because of the loss or theft of a privileged credential. Experts have been exploring Active Directory infrastructure to identify key threats and establish best practices for keeping data safe. Attend this month’s webinar to learn more.

Yes, a big one. In C++, a struct can have constructors, destructors and methods. You can inherit from a C++ struct and you can derive from it. Plus you can control access to structs by adding protected and private members. They are like classes in C++ with the only difference being the default accessibility as I mentioned above.

So, struct and class in C++ are almost identical. Fantastico! :)

BTW, you have answered to the 11-th question:
11. Can we use  public and private in structures? :)
