What is the outcome of not defining a copy-constructor in a C++ class?

  1. The program will not compile

  2. The compiler generates a default copy-constructor

  3. The object cannot be copied

  4. A runtime error occurs

The correct answer is: The compiler generates a default copy-constructor

If a copy-constructor is not defined in a C++ class, the compiler will automatically generate a default copy-constructor. This can lead to unexpected behavior if the object contains pointers or other resources that need to be properly managed during copying. Option A is incorrect because the program will still compile, while option C is incorrect because the object can still be copied, but it may not behave as desired. Option D is incorrect because a runtime error will only occur if there is a specific coding error that causes it, not due to the lack of a copy-constructor.
