Multiple inheritance would really complicate the language, and
it's benefits are held not to be sufficient to outweigh the
downside of that.
Another very important thing to bear in mind is to prefer
composition over inheritance - a simple maxim but very very true
(IMO). Google it for more details.
In the seventies and eighties oject orientation was very
fashionable and books like "Learn C++ in 24 hrs" were mainly
filled with the complexities of inheritance. This made us think
that inheritance was the preferred way to share functionality
between classes of objects. As it turns out, it's not (IMO).
