By using multiple inheritance as you suggest, class c inherits from class a *twice*, thereby having double copies of all instance variables declared in a. This is bad. Consider how difficult it is to manage a multiple-path inheritance in C++, and how that has rendered necessary the use of "virtual" memember objects.
