Class copy constructor and assignment operator

Explain why it is essential that a class that dynamically allocate memory in the constructor also needs a properly written copy constructor and assignment operator.

Is the above question related to memory leaks? How would we know if we have 'improperly' written the copy constructor and assignment operator? What are the pre-emptive measures?

"What are the two ways of achieving automatic type conversion from an object of class X into an object of class Y?"

Thanks.
