Need of privatizing assignment operator in a Singleton class

Question

Can someone justify the need of privatizing the assignment operator in a Singleton class implementation?

What problem does it solve by making Singleton& o

Answer 1

When you use a singleton the reason you implement it is because you only want one instance of an object of that class. In other words there is no need to make a copy of the instance because you can only have one instance. It is the same for the copy constructor.
