Order of construction with a base and a member
Question
Class B publicly inherits from class A and contains a data member of class C. When a B object is created and later destroyed, in what order do the constructors and destructors of A, B and C execute?
Short answer
Construct , then , then ; destroy , then , then . Base classes are built first, then members in declaration order, then the derived constructor body runs. Destruction is the exact reverse.
