There are plenty of situations which multiple inheritance can model better than single inheritance.

The most obvious one is a Person class which inherits from both a Mother and a Father class.

Check out this link which has some class diagrams for multiple inheritance in C++ including one for the 'diamond' problem where a class inherits from two classes which each inherit from a single base class:

@vulpes i didn't know, why would a class have more then one parents classes? to me that doesn't make sense, can you please send a class diagram for those classes if you can?

@Mongezi,

Yes, there are languages which support multiple inheritance despite the ambiguities which this entails.

They include well known languages such as C++, Eiffel, Perl and Python.

Yes u can if only they is one parent class and all the child classes code are going to inherit from the same class

@Vulpes does that mean there are languages that support multiple inheritance, like one class that have more than one parent classes?

Yes, as long as each class doesn't have more than one parent.

C# doesn't support multiple inheritance where a class can have two or more parent classes.
