Question

This is just a quick question to understand correctly what happens when you create a class with a constructor like this:

class A
{
  public:
    A() {}
};

I know that no default constructor is generated since it is already defined but are copy and assignment constructors generated by the compiler or in other words do i need to
declare a private copy constructor and a private assignment operator in order to prevent this from happening?

class A
{
  private:
    // needed to prevent automatic generation?
    A( const A& );
    A& operator=( const A& );
  public:
    A() {}
};

Answer 1

Yes. The copy constructor, assignment operator, and destructor are always created regardless of other constructors and operators.

If you want to disable one, what you’ve got there is perfect. It’s quite common too.
