hello friends. i have a question
if we don't define the kind of inheritance(public or private)
by default is the inheritance private?
for example if i write

C++

class A
{ 
};
class B:A
{
};

is similar to

C++

class A
{
};
class B:private A
{
};

is it true?
please help me. thanks

Just like with unspecified member of a class, if you do not specify the access when you declare the inheritance it defaults to private.

So yes, your two examples are equivalent.
I'd personally prefer to see the latter form though, just as I prefer to see the access specified for members of a class.

Sidenote: when applying inheritance to structs, the default is public. Of course you can derive a struct from a class and vice versa, in which case the default depends on the type inherited from.
