how much does the default destructor do

Question

Does the default destructor in C++ classes automatically delete members that are not explicitly allocated in code? For example:

class C {
  public:
    C() {}
           


        

Answer 1

The implicitly defined (default) destructor will call the destructor for each member. In the case of a member array, it will call the destructor for each element of the array.

Note that pointers don't have destructors; you need to manually delete them. You don't have this problem in the provided example, but it's something to be aware of.
