Problems with multiple inheritance
Let us understand the major reason why multiple inheritance is considered problematic
Concrete problem
In a C object
ac
: Which
x
does
ac.x
refer to?
General problems
The name clash problem:
Does x in C refer to the x in A or the x in B?
The combination problem:
Can x in A and x in B combined to a single x in C?
The selection problem:
Do we have means in C to select either x in A or x in B?
The replication problem:
Is there one or two x pieces in C?
