Implementing the copy constructor in terms of operator=

Question

If the operator= is properly defined, is it OK to use the following as copy constructor?

MyClass::MyClass(MyClass const &_copy)
{
    *this          


        

Answer 1

It is more advisable to implement operator= in terms of an exception safe copy constructor. See Example 4. in this from Herb Sutter for an explanation of the technique and why it's a good idea.
