In one class named Contact, It has private name(string) member, and the second class (base class) AddressBook, has private member Contact contacts[100], and I can't acces when I define in main like this:

AddressBook ab1;
cout<<"Enter Name"<<endl;
name=ab1.contacts[0].setName();

If `contacts` is `private` than you are not meant to access it. The `AddressBook` class will probably offer a member function to access contacts. – François Andrieux Dec 03 '20 at 19:39

Does this answer your question? [Difference between private, public, and protected inheritance](https://stackoverflow.com/questions/860339/difference-between-private-public-and-protected-inheritance) – Orion the Constellation Dec 03 '20 at 19:39
Sidenote: Instead of storing a fixed number of 100 `Contract`s, use a `std::vector` and store the amount of contracts needed. – Ted Lyngmo Dec 03 '20 at 19:47
how can I exactly do that ? I mean how can I assign a vector value to array ? – JuanDoe Dec 03 '20 at 19:48
you might wanna read up on encapsulation and what it's purposes are – Yamahari Dec 03 '20 at 19:48

@Monstarules no matter how you inherit you cannot access a member that is private in the base. Thats not a duplicate – 463035818_is_not_an_ai Dec 03 '20 at 19:57
@largest_prime_is_463035818 actually the answer as to why he can't do that is in there. François already answered the question in the comments for him as well. – Orion the Constellation Dec 03 '20 at 20:03

@Monstarules well on a second thought it might be the right duplcate – 463035818_is_not_an_ai Dec 03 '20 at 20:06
