C++ - Inheritance

When class B is inherited from class A, first class A's constructors are called and then class B's constructors are called. Because it indicates that class B is the base class and class A is a derived class.

Poor wording

You should rephrase this question. If "class B is inherited from class A", that tends to indicate that B is the base class. At best it's ambiguous.
